extremely poor service

I purchased the a decoder (explora). in this contract (R899 pm) the eplora must have been delivered to me, installation free of charge. The decoder was delivered to me on Friday(30/10/2015) and I received an sms confirming that my account was immediately active and I am therefor being charged for daily. however, until today multichoice has not sent anyone to come and install my explora . after I spoke to them on the following Monday (02/11/2015) they apologized and promised to either install it the same day or the following day, that was Tuesday the3rd of November (Case number 273 as per reported by me). when nobody contacted me by Tuesday by 14h00, I again phoned Multichoice (this time case number ***). they again apologized and said it is unacceptable for a client to be treated like that. he again escalated the matter and said that it will be done within 24 hours. at 14h30 Wednesday the 4th of November I again contacted Multichoice, as yet again nothing happened and nobody contacted whatsoever. I asked to speak to a manager. Nonyha, who promised to phone me back with answers within an half an hour.....still waiting and still paying for benefits I am not receiving!!!
