MTN very useless

I was double debited and NOT to my fault. No courtsey phone call/sms/email from MTN, I had to call them which I was informed that they are aware of the issue that occurred on the 28th December and they can't give me time lines on when they will return my money. For such an established organization you would think proactiveness and communication would be top of mind, I don't know what ****** business they running there. MTN I want my money!
