Disgusting service from Dstv Customer Service

I have had endless issues with dstv. I have had 2 explorer decoders replaced twice in 4 months. Out of pure desperation having ensured wait times of more than 2 hours at a time at the walk in center in randburg on more than 3 occasions I called the call center on Sunday evening, 4th May to upgrade my current package to the new ultra decoder and premium package, might i add that i have always been a premium customer. After speaking to a call center agent, Kgotso Nthunya i was advised that my upgrade was approved and my installation was supposed to be scheduled for 7th May at 8am and that the installer will contact me to confirm. This was after spending approx 1 hour processing the upgrade. To my surprise I received an sms confirmation that my installation is now scheduled for the 15th May. So I called the call center to raise my frustration and was cut off twice, told that the installation times are 7 to 14 days opposed to 3 to 5 days that Kgotso informed me. I advised the agent that I was misinformed and want to cancel my subscription and guess what the retention agent hung up the phone so I here I go again calling the call center and guess what I was cut off again and still have not been able to cancel my subscription upgrade or anything answered.Dstv your service is appalling and your call center agents are absolutely atrocious. You don't deserve customer that are loyal and have been paying for terrible viewing line ups and movies from before I was born. Your entire brand is disgusting. If you reading this, you have jst lost a loyal customer of more than 25 years. Cancel my subscription immediately.
