Learn Turkish: Hiçbir resmî kurum telefonla özel bilgilerinizi doğrulamaz. - No official institution verifies your private information by phone.

You would put it at the beginning: Meğer hiçbir resmî kurum... You use meğer (or meğerse) when expressing surprise about a fact you just discovered. If someone almost got scammed and then learned this rule, they might say: Meğer hiçbir resmî kurum telefonla özel bilgilerinizi doğrulamazmış. Notice we also added the reporting suffix -mış to the verb, which is very common when discovering something new with meğer!

Why does the verb doğrulamaz have a negative ending when the sentence already starts with hiçbir (none/not any)?

In Turkish, words like hiçbir (none/not any), hiç kimse (nobody), and asla (never) always require a negative verb. So literally, you are saying "Not any official institution does not verify." This double negative is grammatically required and sounds completely natural in Turkish.

Why use the aorist negative doğrulamaz instead of the present continuous doğrulamıyor?

The aorist tense (the broad tense) is used for general facts, habits, and timeless rules. Because it is a permanent, official policy that institutions do not do this, doğrulamaz is much more accurate here than doğrulamıyor, which would imply they just aren't doing it right now at this moment.
