Advansia Gebührenfrei

Hey everyone, I have a small doubt regarding the Advansia credit card! Suppose, I got a bill of 300 euros on lets say 3th july, and I have to pay it off by 20th of July!, but when I reach the 20th, the 300 euros has become 400 euros! My question is, if i paid off the 300 before 20th,do i need to pay interest on this remaining 100 euros after the 20th? Or will it be billed during the next cycle? Thanks and regards submitted by /u/AffectionateRain953 [link] [comments]
