Misleading tele-sale

Beware of Vodacom telesales, I have sign up for a data contract for R149. My monthly bill is now R159, where does the R10 come from that was never discussed nor mentioned to me.

I'm sorry but I demand the recording of the sale because this is day light *******. I am really not impressed, we suffer ing already during lockdown and this is so not necessary!

The worst part is calling vodacom customer care as no one is willing to help when you have problems with their service, but they jump for sales deal. I wanted to cancel Vodacom all together and they insisted this deal now look where I am :-(
