I am utterly disgusted and disappointed with Vodacom I received a call saying that they would like to upgrade my existing contract from 1g to 2gigs per month of which i asked several times if i will have to pay more for that and the answer was no the amount will still be there same they just want to upgrade cause im paying more. to my surprise they delivered a box to my workplace and I took it to the Vodacom shop Secunda and they opened it there only to find a new sim card of which i did not even understand whats its for then the guy checked for me what's going on and i was told that they had givenme a new contract for a new line that SIM card and i asked that they cancel it as i had not authorized such and was given the number ********** after sales and was advised that i should never take anything from Vodacom over the phone cause once I accept something from them those people they can give me whatever they like and i will have to pay. I then called the number same day to cancel and the lady I talked with said its not a problem since it was not a device she will just cancel i dont have to return it to them. Came month end November Vodacom took R823 from my account instead of the R539 I always pay called my bank to reverse the money went to Vodacom shop to manually pay. And they checked for me what's happening only to find out it was never cancelled. Please fix this cause now i have been calling nonstop with my own airtime to sort this out im being transferred from one department to another im sick and tired of this as it will mess up my credit score i wont pay for something I don't know and have never used and i cant be reversing my money all the time this is absurd ive never skipped a payment on anything I won't tolerate such in my life i cant suffer because of this nonsense now I always drop calls of telemarketing because of this issue. I won't be billed for something I don't know please fix this before it gets out of order and messes my stuff up I still want to do a lot of stuff in my life and I won't let this inconvenience me. I will only pay the R539 that I know nothing else I don't as i have already wasted my airtime calling to fix this nonstop i will never accept anything from telemarketing such ****** I regret the day I received the call.
