Disappointed customer

I took a price lock early November and the decoder was delivered however it hasn’t been installed as yet. I was promised that they will send an installer and that it’ll be free, a month later I’m still waiting. Month end November I was billed double, I was billed R519 for the normal subscription and another R519 for price lock and on top of that they billed me R50 for a supposed reconnection fee, I don’t know which reconnection fee because every month multi choice debits their money from my account and they always get it. I’ve been calling multichoice for two weeks now and none of my issues have been resolved, they always promise to escalate these matters and they always promise to get back at me but nothing. I’m so disappointed, I know that to multichoice that R569 is nothing but to me it’s a lot of money. I keep my end of the deal all the time, I pay my account every month and on time but they fail to keep their end of the deal.
