Suspended line

On the 20th of July 2015 I woke up suspended line by MTN without notifying me as the client upon calling the call centre I was told that it was suspended as they were on a process of migrating my prepaid number to contract which is a request that I've since loaded in April 2015 but they failed to do until they decided to suspend my line without my knowledge. <br> <br> To date as am writing my complain here my number is still suspended and the prepaid line is still on prepaid meaning am paying for contract that I don't have access to and am forced to buy data while am paying the contract monthly. I don't know what is it that MTN is trying to archive with this because now am double spending with something that could have been resolved 3 months back but they still failing to fix. Am totally not happy with MTN service and the service they are giving me because monthly they deduct R650.00 while I don't even have access to the line. <br> <br> Can someone really take control over this matter before I move to another network because I can't be treated like am not paying while I am. Am tired of MTN service it's totally boring and I can't take it anymore.
