Contract phone

On the 10. 07.2017 I went to Mtn store in Jabulani Mall to get myself and contract phone. I didn't have the phone and was using my dads phone. When I was applying for my contract phone I have give the consultant clear instructions that he must do a sim swap as i wanted to keep my old number. instead he decided to use my dad's cell number on my contract. It's been now 3 months they are not resolving my query and he only phoned me once to tell me that I need to give him the invoice number. I phoned him to check how far they are with the query and he told me that my query is on 80%. I even phoned the so called manager Lee go while the store was renovated. He was not even interested to listen to my query and told me that I need to come after the store renovations. Now my dad's phone is not working for a week and nobody has a decency to give me constant feedback. That's the worse Mtn store in terms of customer service and I think they should train their staff because it looks like they lack attention to details. The customer request this and they do their own thing. Right now am paying every month for the contract phone that am not even getting airtime on. I don't even know when is this matter going to be resolved..
