Unpaid refund

My reference is: ***. Cell C agreed to refund me the bank charges I had incurred due to them debiting my accont when l had given them my new banking details but up to today no refund has been paid to me yet on the other hand the retensions people keep phoning me to upgrade as my lines are due for upgrade. In your senses do you think l can renew my relationship with you when you can't resolve the problem created by you. Don't tell me stories. PAY BACK THE MONEY. PAY BACK THE MONEY. PAY BACK THE MONEY. PAY BACK THE MONEY. PAY BACK THE MONEY. PAY BACK THE MONEY. PAY BACK THE MONEY.
