Shocking DSTV after sales service!

I have had nothing but absolute shocking service from DSTV. Firstly I reinstated my DSTV in the TV that I used when I last had DSTV. Back then I had to buy an add on “tongle” whatever it is called as my TV was not compatible with Showmax. After the purchase I could watch Showmax. Now my TV with the tongle is not compatible anymore. This was not communicated with me when I re-subscribed to DSTV! But that is not what had upset me so much. Fir the last three weeks of trying to watch a movie on box office, phoning the call centre and having my query escalated four times, I am still waiting for them to come back to me and tell me what is wrong. Don’t get me wrong, I have managed to watch one movie, the first and only movie but since then not being able to watch but have been charged for four movies. Shocking. Phoning the call centre and getting the prompts that do not address your problems enough to drive you to drink. DsTv is happy to take the full premium package payment every month which includes box office and showmax but I have neither, shocking! Tried to cancel my subscription tonight but the call centre after 20 calls cannot hear me but then again I was shouting and totally loosing my temper.
