Poor service from DSTV and their technicians.

In November 2021 I upgraded to DSTV ULTRA HD, a technician was sent, and he proceeded to install the decoder and later said that he had forgotten some material for the installation and that he would return the next day to come install it. He then said the connection would work even though the part was missing but assured me that he will be back.It's almost 4 months and he is no where to be found. The connection worked for one day and since then it's off. I reported the matter to DSTV with no help at all besides getting responses that they have escalated the matter. I am paying R768 for something I thought would benefit my family and I but nothing fruitful is Coming out of it. If this matter is not resolved by Wednesday I will cancel my subscription but in the mean time I want a refund on the past three months because firstly you use *****, unprofessional technicians and secondly no one wants to take accountability. All you care about is your subscription that you charge me. I am highly disappointed in your service and I hope someone sorts this out ASAP. Please can someone contact me ASAP.
