Horrible service

Been trying to get my one of extra view connected for the past 4 days which was disconnected by DStv due to upgrade. Called and was assist by an agent who had no clue what she was doing and end up disconnecting my other extra view in the process. She then drop the call after trying to help me for over 20 minutes. Call them back an other agent try’s to help but can not asked to speak to the the supervisor and he too his no clue what he is doing and drop the call that is after 50 minutes between the two who were trying to sort the problem. Called them back again numerous since then but no one knows what is going on .The agents try to help but end up keeping me on the phone for over 20 min and then cut me off when you call back again and ask for a supervisor you have to wait and the process starts again. Been trying every day since and I still have had no joy . After been a loyal customer for over 10 years I am seriously considering disconnecting .
