Dissapointed client

I'm so disappointed about the service I got from them, I paid for Dstv via my FNB application online and I called to reconnect my account after payment was told to send proof of payment of which I did.... 30 minutes after that was told I need to send it In a pdf form then I did..... Saturday was told my proof of payment doesn't meet their requirements of which I don't what are those requirements.... I decided to be in touch with my bank still was told that is the only option that I have used that is appropriate for them to allocate funds...... Upto today they still saying funds haven't reflected in and I should send another proof of payment...... M confused don't know what to do anymore.
