Multichoice incompetency

I am perturbed by the Service I have been getting from Multichoice, I have been sending Complaints, had to call their call centre line nothing seem to be done. I made a payment on the 01st of May to their bank account but they cant seem to trace this payment what is confusing me is this, I paid to this account a previous month the only mistake i have made on my End was to use my name as the reference, but i tried to get the correct reference from them with no luck hence I ended up using my name. This has been going On since first of May you can imagine the frustration and the convenience this has caused me, I get disconnected and I have to call again explain the issue to different agents spoke with managers my services gets connected and i should know after 5days I must call again. They all useless and *********** when you calling the call centre you will be put on hold, this has cost me so much and it will affect my credit score.
