Products sold under false pretences

A router was sold to me under false pretences, I was told by the consultant that my cell phone account will never be more than R1200.00 per month if I accept the contract of this router. my first bill arrived and was R2800.00. I have been struggling with the people working at this company for three weeks now. The Reception Cledell is absolutely rude and has no respect for clients, and customers, she has a bad attitude, and is very rude.

the "manager" Sasha never returns your calls.

the Customer care line - never answers their phone, or responds to emails.

I have been told that the respective above mentioned router will be collected, contract cancelled and credit be done, I am still waiting, The next billing date is fast approaching, and nothing has been done. On top of that, I have never given permission to Vodacom and or Rewardsco to contact me. I never signed a marketing consent. for any marketing to be done.

I would like to know what legal action can I take? how do I get rid of this headache and bad service ?

I would like to make this public, as I am sure they catch a lot of innocent people with this issues.
