Incorrect Infomation

I went into the blue route mall store with my wife to upgrade her contract. the sale person advised us that they were running special on the Huawei p (pink)7. He advise that it is being stock piled in the warehouse as they have a lot of these phones in stock due to it not being a popular colour. we agreed on taking that phone and were advised that it would take no more than 2 weeks to arrive. It has now been a month if not more and still no phone. I called in a numerous amount of times and I get told that the phone is out of stock and they don't know when they are getting it and there is nothing they can do about what the other sales person advised us. I have have given up on Vodacom and will look to move my wife's contract to another provider
