Bad service

Wow just wow!!! I've never been so angry at a credit provider for s****ing my name and credit profile through the mud! I've had a loan with this company and paid it up in the year 2016 got a paid up letter etc.... I've recently checked my credit profile and I've noticed they've listed me for R203.25 which they claim is late fees . I called and enquired the lady at the Athlone branch said I should contact their legal department and enquire further.. so I called.... spoke to an utterly rude guy who was extremly sarcastic in his responses to me about the account after I explained to him what my issue was . He then said to me he would contact the branch and find out why this account was not closed and what was going on ... anyways I called back and yet again he had the audacity to be rude again! At this point I was fuming!!! He then said that the "late fees" came after I made x2payments in the same month so that meant the account was paid and no further payments was needed . They have been debitting money from my account and I've been incurring bank charges since then and this ****ed me off even more when I asked him about my charges he said "we were obviously trying to get the money " so rude and abruptly! This is after he said that there was 2payments! I want my bank charges paid for!!! It a over R1500 and I am not going to pay it because I don't see why any of this is my fault since I've paid what i was supposed to? I've requested to speak to his manager and he put me on hold ... after 2-3mins he comes back and says that the balance on the account will be written off ? Wow?? I've requested a paid up letter via email and within a fee minutes I got the letter stating my account is paid up . I am so annoyed for the fact that this affected my credit profile and scoring for 2years!!!! And I've got bank charges!!!! I hope I'll get this resolved and that my bank charges are paid for!!! I will not be leaving this like it is... #annoyed beyond measure!!!
