때문에 means because of or due to.

In this sentence, 거짓말 때문에 means because of the lie or due to the lie.

A very common pattern is:

• noun + 때문에 = because of noun

Examples:

• 비 때문에 = because of the rain
• 일 때문에 = because of work
• 교통 체증 때문에 = because of traffic

So here:

• 거짓말 때문에 고객 센터에 다시 문의했습니다
• Because of the lie, I contacted the customer center again

Because 때문에 itself attaches directly to a noun.

So you say:

• 거짓말 때문에
• not 거짓말을 때문에
• not 거짓말이 때문에

This is just the normal grammar pattern:

• noun + 때문에

So 거짓말 does not need an extra particle here.

They are opposites in tone.

• 때문에 is usually neutral or negative: because of, due to
• 덕분에 is positive: thanks to

So:

• 거짓말 때문에 = because of the lie
• 도움 덕분에 = thanks to the help

In your sentence, 때문에 makes sense because a lie is normally something negative or problematic.

문의했습니다 is the formal past form of 문의하다, which means to inquire, to ask for information, or to contact for a question/request.

Breakdown:

• 문의하다 = to inquire
• 문의했- = inquired / contacted
• -습니다 = formal polite ending

So 문의했습니다 means:

• inquired
• contacted
• asked depending on context

In customer service situations, 문의하다 sounds more formal and professional than everyday 물어보다.

문의하다 is more formal and is very common for customer service, business, websites, offices, and official communication.

Compare:

• 물어보다 = to ask, to ask someone a question
  More everyday and conversational
• 문의하다 = to inquire, to contact for information
  More formal and service/business-like

So if you contact a company or customer center, 문의하다 sounds much more natural.

Examples:

• 친구에게 물어봤어요 = I asked my friend
• 고객센터에 문의했어요 = I contacted the customer center / made an inquiry to customer service

Here, 에 marks the target or destination of the inquiry.

With 문의하다, Korean commonly uses:

• 장소/기관 + 에 문의하다

So:

• 고객 센터에 문의했습니다 = contacted the customer center / made an inquiry to the customer center

Even though 에 often means to, at, or in, here it works naturally with the verb 문의하다 to show where the inquiry was directed.

Usually, 에 문의하다 is the most natural pattern here.

• 고객센터에 문의하다 = the standard, natural expression

Using 에게 or 한테 is more common with actual people in many other verbs, but with 문의하다, 에 is the usual choice, especially for offices, departments, websites, and customer service.

So for this sentence, 고객 센터에 is the best fit.

다시 means again, and it modifies the verb 문의했습니다.

So:

• 다시 문의했습니다 = contacted/inquired again

It tells you the action happened one more time.

Korean adverbs like 다시 usually come before the verb they modify, which is exactly what happens here.

Because Korean is generally a subject-object-verb language, and the verb usually comes at the end.

So in this sentence, all the background information comes first:

• reason: 거짓말 때문에
• target/place: 고객 센터에
• adverb: 다시

Then the action appears at the end:

• 문의했습니다

That word order is very normal in Korean.

Both are correct, but they have different levels of formality.

• 문의했습니다 = formal polite
• 문의했어요 = standard polite, less formal

Since 문의하다 is already a somewhat formal word, 문의했습니다 sounds especially natural in writing, reports, official explanations, or polite customer-service-related contexts.

If you were speaking casually but politely, you could also say:

• 거짓말 때문에 고객 센터에 다시 문의했어요.

In real usage, 고객센터 is very common as one word.

You may also see 고객 센터, and it is understandable, but 고객센터 often looks more natural in modern everyday writing, especially for the name of a customer service department.

So learners will commonly encounter:

• 고객센터에 문의했습니다

If you want a very practical takeaway, remember 고객센터 as the most common form.

Korean nouns usually do not show articles like a or the, and they often do not mark plural unless needed.

So 거짓말 can mean:

• a lie
• the lie
• lies

The exact meaning depends on context.

That is why English translations can vary, even though the Korean stays the same.

It can be used with both nouns and verb-based clauses, but the form changes.

1. With nouns:

   • 명사 + 때문에
   • 거짓말 때문에 = because of the lie

2. With verbs/adjectives:

   • -기 때문에
   • 늦었기 때문에 = because I was late
   • 바쁘기 때문에 = because I am busy

So in your sentence, 거짓말 is a noun, which is why it is simply:

• 거짓말 때문에 not
• 거짓말기 때문에
