So disgusted by poor or rather lack of service

I have a cr card with Standard bank. I received an sms informing me that my account will be sent to legal department due to late payments, after which I made 2 payments of R1 000 each, one on 21 Jan 2016, another on 27 Jan 2016. I never got any sms confirming receipt of payments. I have been calling them since the beginning of the week and I have been to their branch twice already in this week alone. Call centre tells me they cant provide me with the balance cos they cant see what it is. Balance owing per 06 Jan statement was R12 300 and they say I am still owing the same amount. Branch cant provide me with the balance and refer me to the legal department. Legal department consultant can not provide me with the balance and refers my case to someone else who would call me back......who by the way never calls. I am so disgusted by this and I just want to settle and close this account and cut all ties with this *********** Std bank.
