UPSET CLIENT WITH VODACOM

I had a contract with Vodacom where I was paying R85.00 for a 1 GB data , so I got a call regarding the update from a company called ELTEL but they were calling on behalf of VODACOM, The upgrade was specified that I am not gonna pay R75.00 , who wouldn't take that, R10 less for same service , end of July VODACOM deducted R256.00 and I called my back to reverse the amount , because I didn't know was what for , I was expecting a debit of R75 from Vodacom , I then called Vodacom , They gave me the number for ELTEL as the upgrade was done by them , I then called ELTEL , I spoke to CLARISE MBOMBA who was not very helpful , I have the recording for the call ,I got it from her , and she advised me that unfortunately they can not do anything about my query , the last email she sent to me was very unprofessional its goes like this "Hi Akhona ********** 246(reverse and please refund client as she was over charged)- we cannot reverse line that was done over a month ago".

I asked them to cancel the upgrade and put my account to where it was , and I continued paying the R85.00 monthly but now my account is sitting on arrears due the VODACOM /ELTEL, It is affecting my credit scoring . Please see below for my head office response.
