Wrong billing( data billed but not received)

Last year in march I changed my contract to top-up after a long dispute of exorbitant charges to my account. The change was duly effected and was told that the new package did not include data( 300 data for contract) which was part of the contract all along. I agreed because it then would subsequently follow that the charge for that data will not be billed to my account anymore since I would not be receiving the data no more.however, after such change the new billing documents came inclusive of the R 60.79 charge for the data I was not receiving. I immediately lodged a query with MTN for which I was given a ref. Number and was promised that the matter will be escalated n resolve as soon as possible. It has now been 9 months of following up on the matter and each time I do that I'm given a new ref, no. For a new query Because the old one can't be tikraced. As things stand I sit with multiple ref no. for queries which disappear each time I make a follow up. So I'm just stuck with multiple ref no.s and no solution <br> <br> I'm so tired of lack of professionalism, poor business practice and sheer and utter incompetence demonstrated by MTN and its workers. I do right by you so reciprocate!!!
