On 22/01/2016 Vodacom phoned me offering me a wifi - 2 gig for R109.00/month. I struggled and could not use the wifi. On 30/01/2016 I spoke to Denzel and cancelled my contract.

On 15/02/2016 I received my account statement but the R109.00 was included. I phoned them on 16/02/201and asked them to rectify it for the contract was cancelled . on 29/02/2016 the amount of R109.00 was deducted from my banking account. On 3/03/2016 I phoned and the lady said that nothing was recorded on my account that the contract was cancelled. She said that she will come back to me within 48 hours. NO ON CAME BACK to me. On 8/03/2016 I went through to Vodacom Welkom and Richard tried to assist me.
