Terrible Service

I received a bill for the month of May for R2474 for data usage, I queried the bill on the 10 June 2015 and requested a detailed itemised bill for the data usage and to date my query has not been resolved. I called in a week later to do a follow up as I did not receive the breakdown as requested only to be told a query was not logged on my initial call, I have done numerous follow ups only to be told the query was only logged on the 25th June 2015. The consultants provide no help and cannot provide any answers, they either transfer me to a different consultant or they are cutting the call, Its pathetic customer service. I am really considering taking a buy out of this contract and moving to a different service provider as I am really tired and frustrated by the auto page handles queries!!!!
