Poor customer service and misrepresentation

19th Jan I went to above branch for a 2gb internet bundle 24month contract sjm only.Kyle phoned me to say it was approved n I can collect next day.Upon my arrival I asked him about when payment are due and what happens to remaining gb.His reply was that payment will go off with existing contract n data will be carried over.I had to pay for sim card which he didnt tell me about n he never mentioned any connection fees in 24 hrs.I do have a contract by vodacom but it was done via telephone so I have no knowledge about sim card n cknnectin fees. His lack of information let to following.R139 deducted from bank which there was no funds for. According to contract only R97 was suppose to be deducted.I reported it to his manager and vodackm customer care I now have to pay R139 plus R100 penalty fees cause he didnt inform his client. Manager response they are not liable n have reprimanded him.I refuse to lay penalty fees n I hold store responsible for this mess. I have ask that store owner Mr Blom contact me and 2 days later i have not gotten a call or email. This matter reflect no kn my record n I want this matter resolved as soon as possible.
