No support from call centre after victim of *****

I have been the unfortunate victim of ***** on my data contract with Vodacom. Someone from Vodacom's anti-***** department called me and asked if I requested an upgrade to my data contract, which I did not, and they mentioned they suspected I was the victim of *****. They said they would review and reverse the ******* transaction. I had to call back and confirm that the case was solved. Twice I did so, and twice the agent said they would escalate the matter as they could not confirm or deny the issue had been resolved. Today I got a shock sms that the ******* upgrade had been completed. <br> <br> I have logged numerous queries with Vodacom regarding this, but no success to date. Every time I speak to the call centre, they tell me they will log a query...I honestly do not know what to do anymore
