Suspended Line due to Error on MTN

MTN South Africa! You suspended my line this morning, as apparently I have an overdue account of R1 234,77! This has never reflected on any statement received from you!

On further investigation (I had to go into a branch), it turns out that in 2009 you MTN underbilled me on a contract! 8 years later you decide to suspend my line! You could have told me about this each time I upgraded my phone (4 times in the last 8 years).

I am now told I need to pay this amount before I can be reconnected, even though I had no prior knowledge of this amount owing, and it was an oversight on MTN's side!

I will be cancelling the one phone I have with you at the end of November, and as soon as this current contract expires, will cancel the second phone.

Way to Go MTN! Really Super Efficient (NOT!)
