poor service from FNB

January 15 i made an arrangement to pay my non overdraft fnb account which was overdrawn. on the 26th they deducted the whole amount which i was owing. for the past week i have been trying to get them to have the arrangement cancelled but no one seems to be willing to assist. on monday, 5 february i was told the arrangement has been removed but when i check my app it is still there. called their call center and they keep on transferring my call . its so frustrating
