Useless service from DSTV Multichoice

On the 12th April I send an e mail to Help at DSTV requesting a change of ownership. I got no response. The same mail was sent on the 20th April, and again no response. The WhatsApp does not work, as you try to speak to a robot which is not human and don't understand. After several calls to their customer center, I spoke to a Patricia who said she would help. A very bad line and after confirming her e mail address, I sent the mail only to be returned as not delivered. DSTV is very quick to let you know if they did not receive payment, but useless to assist when you need them. As a premium customer I expect service from them. If they cannot employ people who can do the job properly, they should get rid of them. I would like an answer from DSTV asap. If no response, I will go the route of many and just not pay my account, until such time as the matter has been amicable resolved.
