Bad service

I have had my contract for 2 yearsand had my number for several more years through vodacom now and in September 2014 I had requested that I wanted premature cancellation, which I had completed all forms ect made payment and yet the contract was not cancelled so when calling I was advised that the funds paid would be used in place of my debit order however upon calling today 20/2/2015 there will still be another debit order whats worse is the consultant cant even advise of amount that going to be debited <br> I have always trusted in Vodacom I am starting to doubt now...<br> I would like feedback <br> <br> loyal customer!!!
