Price lock cancelation

I am very upset with the way I am being dealt with to my query. I app**** for the black friday special, however it was delivered today and I called the call Centre today I spoke to 4 different agents as I had a price lock on my previous subscription I want it either to be canceled or put on my new one. The first person I spoke to drop the line, second one told me I will be liable for my full balance for the rest of the 11 months, third one was very polite explained well told me she will let them call me back but I will only pay cancelation fee. When the installer came I had to call them to do the subscription the guy says he don't do canceling he will get someone to call me if the dstv doesn't connect in 2.hours as I also receive a error on my side till until now now called. I then received a call from someone a few minutes ago saying she received a escalation that she needs to phone me, she then says she will try to put me through to another department then she also dropped. I am trying to get through on the Facebook page but it seems like I'm going nowhere I'm so ****ed off
