BAD SERVICE ALL ROUND FROM VODACOM

I received a call from Vodacom saying I got a free laptop and and a speaker for being a valued client. I asked them 3 times is this an upgrade to which I was told that it wasn't and I was being rewarded for being a good customer. A few days later I pop into a Vodacom store, to be told that one of my contracts was upgraded - which I didn't agree to. I was told to call Vodacom as they couldn't help me instore (which I still don't understand) I called them twice and they said they would review the call and get back to me. Well 5 months down the line and no one has gotten back to me. Nothing has been resolved. Im now paying for something I didn't agree to, I have a laptop which hasn't worked since I got it. Thanks Vodacom for NOTHING!!! Bad service all round. Nothing was resolved, still sitting with things that don't work and a new contract which I didn't agree to! HORRIBLE service! I would NOT recommend anyone talk to VODACOM or take out a contract with them. I would rate them half a star!!! Thanks for nothing VODACOM!
