********** Upgrade

After being a loyal customer for 16 years. This is the service I get. I have a 3g contract account called my gig2 which expires end of Feb and other contracts. Upon checking my statement this month I see that my 3g account has been upgraded to what is called UChoose Smart S. Which I did not ask for or even went to the shop to do. Now this will bring my payment for the month of Feb to R1081.54 from R744.50. I did not do an upgrade and I do not even have that handset the statement is mentioning for R270. It is not in my position. This is very clear that some ***** happened here and no one seems to be able to give me clear answers. Now my bank account will be debited with an amount that is extra by R337.04 that I do not have and did not plan for. Then I was told that they cannot reverse the system, this amount will go through and who will take up the bank charges that will occur because of this mishap. I cannot even make follow up on a reference number that I was given, I am sent from pillar to post at the call centre. I will give my bank an instruction not to pay this amount, I will make the payment myself. Or must I hire a van with a poster and park it by the N1 next to Vodacom???
