I have spoken to consultants from Sam Ntuli and Lemontree and they have not been of any help to me I need a solution as they not managed to help me at all

I opened an account at Pep and I didn't buy anything but for some reason I have accumulated a balance of 96rands it's not the 1st time they asked me to pay ,I payed because they said it was insurance on the card so I canceled the insurance and asked for the account to be closed but I am being sent from pillar to post and as long as the account stays open it accumulates a balance of which I am not prepared to pay because I have never used the account When I spoke to them about closing the account they tell me they need my bank statement which doesn't make sense because I just need my account to be closed This will ruin my credit score please help
