Bad customer service

I opened an account with them and then went out of work but informed them that I am now unemployed and cannot afford the installment, we then agreed on R160 then after I decided to up my payment to R200.<br> <br> Then when I started working I received a call from them and then made a payment arrangement of R300 per month, so today I decided to make a payment of R1400 as I have promised Mia I will get her a Tablet anyway I made the payment and then asked the teller how much I can buy for, he told me R1900 so I took two pairs of shows for myself and a few things for my sisters unborn baby, when I got to the till again to pay the guy told me there is a block on my card.<br> <br> We then called the customer service to ask where this is coming from and they then told me its because I was in arrears, but then I asked them why they failed to inform about this block, the first two people hung up the line on me I called back to speak to the manager then the third consultant put me through to him (Nevin) he then tried to blame the teller but they were the people who called me about my payment arrangements and not the teller.<br>
