Rain- Customer service - absolute joke!!!

I have received absolutely disgusting customer service from your call centre and my issue has still not yet been resolved. I have asked many of the agents I spoke with for a complaints number but they have failed to provide one. I cancelled my service 3 months ago yet the cancellation was not done and I was debited roughly R1400 this month for services that I did not use. I’ve been given the run around every time I call through the call centre. I been promised call-backs from team managers that have never been received. I just got off the phone from an agent by the name of Naledi whose team manager Racheal refused to take a call to ease my frustration saying, “she was busy” and she is the only manager on the floor - this speaks exactly to the type of customer service I have been receiving- So after numerous phone calls and emails - still nobody can confirm that my refund has been processed. Nobody has been in contact to understand my issue or demonstrate any form of accountability for the situation and worst of all NOBODY has a clue of if the people they work for has a complaints team !!!
