Billed for Services Not Provided

I dont understand why this company is so BAD at getting back to their customers!!! I received an upgrade and signed a new contract for 2 years and they automatically cancelled my data bundle without informing me, after Mr Marco Adonis after numerous phonecalls earlier this year PROMISED that this would not happen. Funnily enough I have been charged an administration fee of R20 for a MTN data bundle I do not have . This has incurred huge costs to me over a 3 month period. I called on wednesday to customer services Mr Freddy Skosana, and he assured me I would get a call from a team leader that day. I then called the next day 24 June 2015 and Twana said I would get a call by the end of that day, No one has called as yet. I am so sick and tired of this company I cannot tell you. I expect a refund for 3 months of data useage that I had a data bundle which was confirmed by Mr Adonis. Please everyone check what autopage is charging you for, clearly they charge as they wish. I still am waiting for a response. Ref 736337
