*********** DSTV

I have been with DSTV (Multi choice) for some time now. I am currently on a price lock with DSTV and on a previous occasion. To my understanding, price lock as they advertise it means that the price you pay is locked for the 2 yr contract. My price has fluctuated and is not "locked" as DSTV sells it, so what is the point DSTV advertises it so. I have also called the call center numerous times and tried to get someone from the price lock department to call me back, no chance in hell that has happened and I don't think this is going to happen.
