payment not allocated to my dstv acc

I paid my dstv account end March 2016 and used my name as a reference to the value of approximately R1150.00 however the money does not appear in account so i keep on getting being disconnected. I called 5times for assistance and no one wants to help i have sent each and every agent i spoke to the proof of payment then they would reconnect my services but that comes with a charge. I asked to speak to anyone in finance to assist in locating the money into my account to avoid being disconnected again but i was told it was impossible to talk to finance. I have been disconnected 3 or 4times because of this and my bill goes high everytime they reconnect my services. I hate complaning but if it will help i have no choice. This morning i was disconnected again, i am tired of calling without any assistance. I need the money that i paid to allocated to my account and every reconnection fee that resulted from this to be removed from my bill. Your help will be highly appreciated.
