Bad service

I made an agreement with DMC to settle my account. The agreement was that I pay R1000 for 2 months then the account will be settled. I paid in February and March which was supposed to be the last payment. To my surprise they debited my account again on the 25 April when I called to ask why none of their agents could tell me why my account was debited again instead I was advised to go and do a reversal at the bank. I sent an email to Pamela Nqeto who is the supervisor on the 2 May but she never rep****, whenever I call the call centre she is not at her desk or attending a meeting. I have the paid up letter that was emailed to me but I do not get why they are not refunding my money back. Every time when you call the call centre you get a different story. Today I spoke to another agent Terchia Solomons who was also very rude.

This is unacceptable, their service is pathetic.
