Billed for on the 13th month for promotional data that was to expire at the end of the 12th month

I have been billed without consent for promotional data that was part of the original package. This data was to end after the 12th month but has been billed to my account.

I have been contacting the call center on a weekly basis since I picked this up on the 21/07/2017. I have refused to pay this amount and a credit has been promised but so far nothing has happened. It is shocking that no one is able to contact anyone in billing. I have multiple reference numbers. Something that should take a accounts person 5min to sort out has to be dragged into a long process that has had my contracts suspended on two occasions. Multiple managers promising to call me back and agents telling me that my account will stay blocked until the "Investigation" is complete. This "Investigation" should ultimately lead to MTN being liable for *****/theft. I wonder what is to happen if someone is not watching their monthly statements and have their accounts on debit order.

Extremely poor service from MTN. No customer service received at all. Your front line support is friendly but is of no use if a billing issue arises as they can do nothing but escalate and even this does not seem to yield any results. Please can someone from MTN finally resolve my issue and provide proper and meaningful feedbac****
