Terrible nightmare service I have ever experienced

I have a credit card with African in which I have an installment of R1830 per month they are having problems debiting so I make cash payments of R4000-R5000 and I have a listing on ITC because of them, In September 2017 I got over debited after I made a payment in which I asked them to remove a debit order I rather do cash and they confirmed its done which I later discovered its not, I called them since 23rd September and I was told the funds will be refunded in 5 working days, I called again Friday the 29th I got hold of some rude consultant that failed to do their job, Saturday again called got another rude consultant, today again I called I was promised that by 12pm the funds would have been paid, still nothing. I want to be compensated for the airtime I use to call in your call centre and find rude consultants that wasted my time and money and my refund. I last spoke to Nonhlanhla
