NO SERVICE, NO RESPONSE, NO HELP

We have a wifi pocket rooter that we upgraded on because the contract expired. It gave as 20 gig data during the day and 100 gig at night for R299. We upgraded to Fibre in July and is still waiting. After we upgraded our account total stayed the same. Then suddenly November the account total is R300 more, so on 27 November we cancelled the contract for the pocket router. Although the contracted already ended, I had to give 30 days notice. So when the next account came in beginning of December that same wifi pocket router is suddenly more that R1000.00. I have never ever anywhere in the world seen a 20 gig data that cost that much. So we called again. There was a complaint logged for this with a ref number that I have and nothing has been done up to date.. The agent that helped us said that there was notices send to inform us, but to a wrong number that ended on 07950. My Debit order is going off on the 4th. I need Vodacom to sort this out A.S.A.P or I will take this further with the account to be payable for my lawyer by Vodacom
