Poor DSTV Connectivity Service and Poor Communication

I haven't been receiving DSTV connectivity in Sanridge Village (unit 18) for the past 2 weeks and SADV is not interested in assisting us. I've phone them more than 5 times in the past 2 weeks without any clarity as to when are they gonna sort out this issue. In addition to that, they even ignore my emails even email communications from our Estate Manager. I will definitely write a detailed email to the Body Corporate requesting that the contract with SADV be cancelled, if possible.
