An unpleasant surprise

So I called multichoice again today 27/09/2019 about the overbilling after the pricelock offer. I spoke with an agent named Surprise. She could not help me though but gave me a number to call their billing dept on: ***. I confirmed this number with her no less than three times. Of cause this happens to be a fax line. So I had to call back and this time spoke to Cynthia. She said her system shows my call has been escalated already and cannot be escalated everytime I call (for 4 months). She then gave me another number for the billing dept: ***. Of cause this number doesn't exist. So now I call back, but by now they are aware of my number (caller ID) and drops the call everytime the call connects. I guess I'm just too much of a bother. Still paying R783. 34 for compact plus on pricelock when I was supposed to pay R649.00 four months later. Maybe I should apologize to Mc for being such a pest
