shameful/disgusting service from Mr Price

Mr Price account department is the worst to deal with, I was behind with my payment for few months, and in trying to bring my account up-to-date with payments, every time when I make a payment, Mr Price they decrease the credit limit with R2000.00 last time I paid my credit limit was R3890.00 with a balance of R4600.00. 1. I requested all those unnecessary fees on my account to be cancelled and the fees be reversed, I mean I don't want to use the card anymore I just want to settle it and close the account. they refused to cancel the Customer Protection Plan Opt 1 and Lost Card Protection, if I loose my card, you can charge me when I request a new one. 2. they refused to recalculate my installment, with my being R7700.00 and owing R4100.00, how can my installment be R770.00, I asked for the percentage they are using in calculating the installment and they refused. 3. They reduced my credit limit without my Authority. 4. every time when I pay, e,g when I pay R770.00 they reduce the limit by R2000.00 leaving my account overdue by +-R2000, making me in arrears with R2100.00

I've never in my life experienced such a shameful/disgusting service, only 4 things I need you (Mr Price ) to do. 1. bring back my limit to R7700.00 2. clear my name on ITC as a slow payer 3. recalculate the installment 4. every time when I pay, reduce the limit with the limit with the amount I paid so I don't use the account as that's what you want.
