Worst network provider in SA

I had a contract with cell c and paid a cancellation fee in June this year. In October my account was debited wich was not supposed to happen..after numerous calls to the customer care of cell c and a complaint after days of waiting my funds was reversed into my account. The person from the marketing department contacted me after the complaint was logged on Hello Peter and informed me that my contract wasn't cancelled properly on their system.The funds was reversed and all was good. Today I got an sms stating that more than R500 was debited from my account from cell c. I called in and spoke to Xolani (A very nice guy ) I asked for a team leader and after being on hold for more than 11 minutes I was informed that the team leader was on another call (Which I don't believe) it takes one minute to see if someone is on a call not 11 minutes! The debit order was in contravention of my authority! The funds that was debited will be used for a doctor's bill on Friday. I want MY money back asap!! This is the second time my contract was not cancelled properly I hope the people responsible are dealt with accordingly. Such people really does damage your brand cell c! I'm done with cell c and all of my friends and family members who are currently using cell c will know my story . This is unacceptable!!!!!. Call reference number : ********** ********** 49
