Vodacom is inefficient

Vodacom called me after I put them on hello Peter the manager spoke to me I requested the voice recording when the upgrade was done on my contact the manager then said I should go to my nearest Vodacom store and the recording will be sent to the store she asked me which store I told her the liberty Midlands mall in Pietermaritzburg she requested I go to the store listen to the recording and then we will move forward from there when I went to the store the recording was not sent I phoned Vodacom again and to date I still didn't get to listen to the recording I personally believe they are preventing me from listening to it because the truth of the amount I should be paying is on this recording which should be 302.59 rand but instead Vodacom is charging me 365 and 359 all this amounts and when I asked them why the amount is not 302.59 they said that vat is added and I have to pay a handset charge which was not mentioned to me ,there will be proof of this on the voice recording ,I also told the consultant that 302.59 is all that I will be paying for the next 3 years and she said yes,I am a diabetic and Vodacom has caused me alot of stress and unnecessary running around I am well prepared to pay the amount I was told for the next 3 years but not the amount I am being charged because if I was told about the extra charges the contract would have been unaffordable and I wouldn't have taken the contract I am requesting that this matter be sorted as soon as possible as I am frustrated from February 2022 and it is now November and nothing has been done.
