Cotract port issue's

Hi, I was a customer by autopage on the MTN MY Choose 50 and somehow when I got billed by MTN they billed me for the MTN anytime 200 - and on that account I cant put any limits on. I was nice enough to call you call centre and wait 30 min for help explain my issue to the service consultant then she put me on hold for 20 min just to pick up the phone and put it down in my ear. ok so what I want done is, I want my contract put back on the MTN MY Choose 50 so I can manage how much airtime I can use, if you do need proof I still have the email from Autopage to show that I am on the MTN My Choose 50 I can send that to you, please email me on *** or call me on *** thanks. Due to the issue of the MTN anytime 200 I went R300 over my limit I don't mind paying it due to I am a nice person. so can we work together to sort this issue out quickly please and thank you.
