Numerous billing issues - want to cancel Price Lock

Good day Since I took out the Price Lock package in the beginning of the year I had numerous issues. First I was billed twice, Then my original Premium subscription was not cancelled after I followed all the instruction provided to me, since then it has been an ongoing issue with my account being in arrears event thou I pay each month.

I phoned yesterday twice to get in contact with the Price Lock department I only get told they will escalate the issue, I cannot be transferred and there is no number for me to call.

I called again today and still the same response, I want to cancel this frustrating package but just cannot get any way to do this, Maybe the only option is not to pay.... Then DSTV will cal me quick.
