DSTV Pricelock hassles

I have been contacted about 2 months ago to do a pricelock on my subscription. Last week Wednesday my DSTV was locked due to non payment according to an SMS I received. Contacting DSTV I was informed that the old contract came to an end but was not switched over to the new contract. Lungile assisted me in getting my DSTV activated again with great and friendly service. YEsterday I received another SMS stating again that I now have to pay more to get my DSTV activated. Again it is disconnected. Contacting them again and then was told DSTV Multichoice cannot assit me in the problem. I have to contact DSTV Pricelock. Have been holding on for 20 mins at a time and no help received so far. Is there someone who knows how to operate the system so that the proper information can be allocated to my contract?
