Horrible Service

I've opened my account in October 2015 and receive an email to collect my card at my nearest store. I went to Centurion mall collected my card I received a pre-agreement statement without any explanation.in November when I made y first purchase coz on the pre-agreement it shows a credit limit of R 9,175.00 but at the store I was told I can only buy for 3,990.00. I made a pmt of R200 end of Nov I was left with a balance of R140. I received a mail with my statement that I must pay R140 plus R340 my installment.Yesterday I went to the store in Church str Pta and I paid R480 on my slip they stated you can still buy for R 1,020.00. I went to Markham to purchase items for my hubby such an imbarresment I was told my acc is expired and I need to re-open a new account. They called head office I spoke to Lungisa gave me Ref no: 12153E1A8 and told me my balance of R 2, 969.01 will be written off I don't have to worry but I told him I need it on black and white. He told me that their calls are recorded what the hell is that suppose to mean. I'm FURIOUS Delicia
