Dstv does not care about their customers

Hi. the reason for my complaint is because last week i called dstv for some assistance with my signal problems and they spoke to me about the new pricelock so i agreed that someone could call me back to explain further. A guy called the next day told me about the special offer and i accepted, he took my banking details. he said i qualified and that someone would still call me back to verify the information.No one called. the next day i called dstv and they could not pick up anything, no changes, i have been worried out of my mind since Thursday as the lady made me fear this was all ***** as she knew nothing and could not even pick up the special, she promised to find out for me and call back urgently but nothing to date, i called back today and yet again no one was helpful at all. i have been with dstv for many years and this is truly disgusting service, i am now considering cancelling all services because you guys do not care about your clients at all, you even sent a sms for me to rate the services after the call and i rated them zero twice but no one cares as no follow up was done. the guy who sold the pricelock to me even **** and said it was the latest explora but it was not. i just want to cancel everything please
