PATHETIC SERVICE

I opened a new cellphone contract in Nov 2018. My previous contract with Vodacom was in my mother's name so I did a change of ownership. Signed all the necessary documents, end of Dec came and they charged my mum for the contract so I went back to Vodacom Claremont on the 2nd of Jan 2019 to ask why, they said the person who I was dealing with did not change the ownership, then and there they did it. Again end of Jan they billed my mum again, so I went back on the 1st of February 2019. So the guy changed it on the system. on the 8 February I get billed for a massive (double) my account amount. I phoned the customer line and they apparently can't give me any answers why I got double billed. The lady I was dealing with spoke in circles and could not answer any of my questions related to this account. This is ABSOLUTELY RIDICULOUS. Can't they see on there system that I have paid for this account every single month. PLEASE THINK TWICE BEFORE OPENING A VODACOM ACCOUNT.
