Disappointed with MTN service.

Dear MTN,

I'm highly disappointed in your service. It's been more than 15 days since l brought the issue to your attention. I have been calling your consultants at your centres for my issue to be addressed and I even went to the shop l took the contract. I took out a contract for R239pm and the credit limit was set to 0. I have a copy of the contract. However, month-end l got a bill for more than R5000 and when l went to your shop l was told you migrated to a new system and in the process, the new system override the credit limit and l was billed for normal data. This error was on your side and l do not see the reason why l must pay the R5000 out of your mistake. We are getting to month-end and my issue has not been addressed and you will surely debt me the R5000. This is a big breach of your contract and you seem to be taking advantage of me because you are a big firm. Your people acknowledged the error was on your side, so why is my query not being addressed.

I have been to MTN Facebook and Twitter accounts and no-one rep**** to me. Yet this is what you said to me when l wrote a direct email "Need help faster? #WeGotU - Chat to our Facebook team or shout out to our Twitter peeps (1 hour response time)".
