Billing

My account was moved from Nashua mobile to MTN direct. I have had no problems with the other service providers but MTN is not a pleasure to do business with. I have a limit set on my accounts because the phones are for my kids. When called the call centre to query one of the numbers I had to hold on for more than 10 minutes before a call centre agent answered my call, this happened a few times when I called in. When I asked the call centre agent why this limit was not carried over, she said MTN can not put limits on the contract, I asked to be put through to manager and she helped me to put limits on again. Now the caller ID does not work. I also queried the higher than normal account, but is still waiting for feedback from 13 Jan 2015. The account normally is R 479.68 per month and reflects as average spent on my billing, the account for December how ever is R 1 961.00. MTN takes no responsibilty for this mistake and I get no feedback why this happened. Hopefully I will get some feed back now, after this complaint
