Dstv price lock

Good Day. I purchased my price lock package some time July. I haven't paid my first installment yet. Before activating the price lock package I requested a quote from dstv and was advised that price lock compact I will be paying R549. 2 consultates confirmed this amount. Then come the day of actually activating the package Lorraine from price lock told me that the price is R569 which I disagreed with her about but finally asked her to escalate the matter as that was not the price quoted before. She promised that someone will be in contact with me within 48 hours but 2 weeks passed and no one called me. When the decoder arrived, the package/box was written that I will pay R549. I called dstv, Mpolayi promised that someone will call me back but that did not happen then I called last Friday 07 Aug, I was also promised that someone will call me back. Until today I'm still waiting for DStv to resolve the issue. I send a DM on Twitter to DStv on Saturday and was advised that someone will call. It's 14:16 11 Aug and no one has called me yet.
