Sending me the wrong phone for my upgrade.

On 19/02/2015 I was contacted by Cell C's upgrade department offering me an LG G3.I said that I will think about it and they agreed to phone me back the next day. The call never came but they tried to deliver the phone to my old residential address as nobody phoned to confirm a delivery address. Luckily I was interested and delivery was agreed upon for today. This morning I received a LG G3 Beat, that's the downgraded version that costs R4000 less. I phoned them and the lady said that I was suppose to get the beat but if don't want it anymore they can organise for collection. There is also more or less a R150 difference per month in contract value on the two phones. Now I have to wait 7days for collection and then I need to phone THEM after 5 days to verify that everything is fine. All I want is the phone you promised me at the rate we agreed upon. Is that so hard to ask for? Just get the basics right!!<br> Lets say you deliver the phone to someone that didn't know the difference and the assumed everything to be okay. You \*****"R4000 on the phone and another R3600 over the two year contract period. Any chance this was on purpose? I bet you don't sell beats and had out the proper G3?"""
