Appalling service!!!!!!!

I am quite appalled by the service I have received from Dstv. To date I have not been called back or emailed, even though I have contacted them a number of times. I asked them to send me my contract which they increased without my consent. I spoke to Lelo who told me she will escalate the matter but 7 days later I still await the email or call. Im so upset and want to cancel my contract.
