Vodacom is just plain useless

I have sent a complaint on Friday last week with regards to a package that I am being billed for that I DID NOT OPT for. Vodacom changed the package on their own accord, and now I have to pay R 309 instead of R 189.,

I AM NOT GOING TO PAY THE PACKAGE THAT I DID NOT CHOOSE>

Vodacom rep**** to my complaint stating that someone will phone me. Till date no one has made contact with me. Are they just going to leave it till after the debit order has gone of my account and then refuse to give me my money back.

This is just out right theft!!
