Questions & Answers about seikyuukikan ga nagai ue ni, nijuuseikyuu mo aru.
A natural reading is:
せいきゅうきかん が ながい うえ に、にじゅうせいきゅう も ある。
- 請求期間 = せいきゅうきかん
- 長い = ながい
- うえに = うえに
- 二重請求 = にじゅうせいきゅう
- ある = ある
うえに means something like on top of that, in addition, or what’s more.
It connects one negative or positive point to another point of the same general kind. In this sentence, it adds another complaint:
- 請求期間が長い = the billing period is long
- うえに、二重請求もある = and on top of that, there are also double charges
So the overall feeling is: Not only is the billing period long, but there are also duplicate charges.
