Meteobank Finance charge

Hello po! New here, gusto ko lang itanong I've only had my CC for 7 mos now. Around Feb nagtry ako magcash advance then paglabas ng SOA may finance charges. Upon researching, meron daw talaga finance charge pag nagcash advance and Cash2go. So natapos na nung April yung Cash2go ko then hindi na rin muna ko nag Cash Advance tapos nung tinignan ko yung SOA ko for May and June both may finance charges pa din.

Can someone explain po if that's normal? Or should I call the bank to request reversal? Nagtry muna din po ako magsearch and wala kong mahanap na sagot. I always pay my balances in full, on or 1 day before the due date so I don't think yun pde maging rason ng finance charge.

Any help po will be appreciated. Thanks so much in advance sa mga sasagot.
