Delayed Refund

On the 24th June'15 I recieved a call from the call centre agent requesting me to make a cash payment as they will not debit me, therefore I made a payment on the 25th. On the 26th I noticed that a deduction was made from my account and I immediately contacted the call centre where they promised me that I will recieve a refund within 7 working days. After seven days with no money paid in to my account I called the call centre again where I spoke to 5 agents and 3 team leaders, the name of the team leaders are: Dumisani Gumede
