Incorrect info costing me extra money &bad service

I used my upgrade for a laptop deal in March 2015.In store I was assured<br> by Shaun twice that the data would stop at 500MB.At home I discovered I<br> wasn't given a copy of my contract &a few days later I still received<br> airtime instead of the sim switching over.Went in to query and was told<br> the migration was never put through &my contract would need to be<br> requested from HQ &that I would be notified when it arrived.Never<br> notified.Went in twice afterwards &was told it still hadn't arrived.On 1<br> August an unauthorised debit order went off of my account after my<br> payment was already made.Went in to query &was told it was because the<br> data was uncapped.When I said I was told differently,I was told that<br> Shaun helped me wrongfully &doesn't work there anymore &I have to sort<br> out the problem myself.Sent an email to MTN,no reply.Phoned the regional<br> manager 4times and only received an sms from him at 16:15 to say that he<br> is busy eating and will phone later.Never phoned me.Went in store 3more<br> times and told I can't be helped as the system is offline (each time)<br> &its my responsibility to check my data usage. Never seen such lousy<br> service in my life!
