USELESS SERVICE!!!!!!

Never in my life have I ever struggled to get a response from a company like I do with DStv They take the wrong amount from debit order and when I try to get in contact with them regarding this matter they completely ignore me, no matter how many times I ask to speak with an agent on WhatsApp. I've tried online now and they simply ended the chat with the lame excuse that I don't respond so they have to "end the chat" but I've been communicating with them the WHOLE DAY now regarding an issue with DStv Stream (that's still not resolved by the way and they take their ****** time to respond) and suddenly when I ask about the wrong amount that was taken from my debit order that's the response I get. I'm disgusted by DStv at this point, no wonder everyone leaves this horrible service provider!! They take more money every month and this is the service we get?! I've been a loyal customer for 25 years but I've had enough now SHAME ON YOU DSTV!!!!!!!!!!
