Please cancel my contract

10 weeks and DSTV have still not delivered. This is the Fifth time that I have to report the same lack of service from DSTV. Every time I am told that the problem is being addressed but NO SERVICE IS DELIVERED!!! I have been waiting for more than 10 weeks now. Is it too much to ask that somebody delivers the DVR and dish??? I have phoned numerous times and the only answer I get is that it was escalated and that I must be patient.". How long must I be patient? Are more than 10 weeks not enough??? Please call me I want to cancel my contract.
