Unattended by dstv

I am frustrated and very drained. I had an explora contract wich i took 23. 08.16 and it expired 23.08.18. From there i called dstv customer service to cancel tge contract. I thwn moved to compact paying monthly. Last year june my services were cut due to no payment received. Since i was goin away for a while i decided not to pay for it. It was owin around R600. Now i am back i want to recconect my services.when i call they are telling me i am owing R2500. Remember i am on compact. How on earth is tgat possible? When i call customer service tgey tell me tgey are escalating. Its been more tha a week now colling evryday and all i get is "we are escalating it". I emailed to helpdesk still no response. I went to the agency stil they did not hlp. Im tired m angry im frustrated. Again very disapointed with the service i am getting from multichoice.
