BAD customer service and unauthorized debit order

My experience with legal and Tax customer care call centre was extremely unpleasant to the say the least. They made a debit order that I did not authorize and was not as per agreement. I then called the customer care line hoping to resolve the issue but instead I was met with two rude consultants who dropped the call on me instead of assisting. The second consultant who's name was Matsepo Maselwane based in Bryston even told me "it's not going to happen" when I asked to speak to her manager Shaun Monabeng more than three times. The consultant was rude kept on interrupting me and absolutely had no empathy. The transaction was uncalled for but worse was the treatment from people who are supposed to be representing the company. I am definitely canceling my service after such a bad experience especially knowing that consultants can do and speak to customers as they please with no consequences whatsoever.
