Mtn

My phone have a problem with charging. So I took it in to mtn 3 weeks ago. I've done my contract online. Then Mtn contact me and said they cant start to work on the phone they need the delivery note that I signed when they delivered my phone. I dont have that note anymore. So I started calling the online mtn to get a copy of that. 3 days in a row I was on the phone 40 t0 50 minutes per day. They put me threw from one to another and then cut me off. Waiting all my time I was holding on to get this solved. There is still no one that can help nie. They all say we will email it to you. Can a email take 3 weeks. I have to pay my contract but my phone is at the atm shop. This is the worst experience I had. I was with Vodacom all the time and never had this problem. I'm so sorry that I've changed to Mtn.
