Irresponsible Staff

I have a account at edgars store in Durban. My account was fully paid up and I had a zero balance. I did not sign up for any insurances and any type of cover on my account. I paid my account for a year not realising that I was being charged for all the extras. After my account was fully paid up I did not purchase anything till July 2017 this year. I did not get any statements since my account was paid in full but when I went to purchase in July 2017 they said that I had a outstanding amount of R424.00 which I queried and they said it was for the insurance benefits. I paid the R424.00 and spoke to the supervisor at pavilion store in Durban and told her that I did not requested any insurances at all when I signed my contract, she inturn contacted the call centre and asked them to cancel the amount and that they must reimburse me the amount of R424.00 I spoke to them as well and they said that they will reimburse me. All edgars calls are recorded and nothing has being cancelled from July 2017 right upto current date. I furnished them with all the documents that were required several times but nothing is being done. I also made a payment of R250.00 for purchase which was R965.00 but now edgars is saying up to current date that I am still owing them R1300.00 when I only purchased for R965.00. I called them many times asking them to resolve the matter but nothing is being sorted out and I have to repeat the same things over and over which is wasting a lot of time. I received a message saying that if I don't pay I will be handed over but how can I be handed over when the fault lies with edgars and not me . I willing to pay once I am fully reimbursed. Please assist.
