Paid but disconnected

I made an eft payment for DStv in September which was never allocated. And then was debited the same amount from my account a few days later. Spoke to over 4 consultants who told me they would allocate the payment to my account yet it got disconnected 4 times in a month. The last agent I spoke to was the absolute worst, rude and abrupt and even went on to cut the call when I asked how long it will take to allocate the payment. This has by far been the worst service from a company that's quick to debit me every month but can't resolve an unallocated payment. P.S Your agents need customer service training, their attitude is disgusting!
