Stay away! Far Far away

I was phoned by a mondo sales person for a upgrade and accepted the upgrade then without consultation my approval my contract (VIP UNLIMITED) was completely changed to something else (red flexi 200) when i complained they said they would have to get the recordings and will get back to me, 3 weeks pasted i heard nothing, so i phoned them after eventually getting their number from vodacom and they told me they see the case is my favour as everything i told them was on the recording but they can give me the package they offered and will collect the phone from me by courier, after leaving me for 3 weeks without being able to use my phone or phone people as i have had a red VIP UNLIMITED for two years they just want to collect the phone and cancel the contract and then a sales person will phone me or i can use their brochure to chose a package????? Seriously? So they just reckon after all the inconvenience and never returning the call( probably because the case was in my favour and not theirs) breach of contract they reckon they will just pick up the phone and all is well?! Thats seriously ********
