still no feedback regarding refund

This is now my 3rd report. I have not had any feed back regarding my refund seen that i was over charged on my wifi after i still had gigs left. I am not interested when the lune was open then changed to a closed line. The facts remain that i still had data from the previous month but was charged for over usage. I would like this sorted out now once and for all as i have been waiting since October and what mtn has done is against the consumer protection act. I was given a new reference from Tim REQ:***. I was told they would get back to me shortly well that was over a month ago. I would like some feed back ASAP as to when i will be receiving my refund. This is unfair. Customers are not treated correctly by mtn. I cant wait to no longer have contracts with mtn considering the poor service a person has to deal with.
