Bad service - Customers do not count

my second review with regards to the company. after my first review I was contacted to try and sort my problem. Now I basically I have to pay for their staff's incompetence. First the lady I cancelled my contract with in May did not cancel my contract so instead of having my last debit order be June, I was debited again in July and then when I queried again, I was told after the help full staff member went back on the voice recordings that I have canceled my contract in May, but that their staff member did not do it. So she asked for a credit note and a refund for the amount that went of in July. not a week later I get a statement from Cell C to day they are debiting my account again end of August. This was when I put my first review on Hello Peter. another helpful staff member again requested a credit note for the July and August invoices and a refund from cell c for the money deducted of my account in July. Moses from head office also contacted me but then because the credit notes was app**** for he could not do anything at that point. I emailed him on Friday afternoon to find out what is going on as I still have not received my refund. Yesterday afternoon I got a reply that basically said that they did nothing wrong and I must pay for their incompetence. I rep**** to his email again, and still have not received a reply. My honest opinion is if you think of getting a contract from them - do not do it. They do not care about their customers.
