MTN REFUSES TO PROCESS MY REFUND

I had an interest of taking a contract with MTN of uncapped WI-FI. Their courier company failed to deliver the router. Then MTN decided to close my account and did not bother to update me. When I did my own enquiries on when the router will be delivered, I was then updated that my contract was cancelled and my account is due for a refund. I was sent from pillar to post for the past 10 days. I am given a new reference number daily and I can be allocated to three if not more consultants daily. They all fail to tell me what the delay is. I am given lame and petty responses that I cannot escalate the matter to anyone at MTN and secondly they are all putting pressure on the banking department to process my payment. This is honestly concerning because my money reflects on their system. To a certain extent I am convinced that this is some strategy to frustrate me until I give up on my money. I was sent a statement last week which also reflects my money but MTN is refusing to pay. I have tried to post on their Facebook page and their inbox but they are still refusing with my money. Good people stay clear of MTN or you will be ****med your money like they've done with me!
