False adverti*****t

I went into store and squired about a new cell phone. I was told by the sales consultant that if I purchased the hauwei phone I was looking at I would get a gift pack free (gift pack had selfie stick and charger etc) I told him I will give it some thought and come back a bit later. After giving it some thought I returned to the store to purchase the phone. After paying for the phone I asked for my gift set which I was told would be included, I was told the rep came to fetch the last gift set but he assured he will get it for me before Christmas as the phone was a gift for my girlfriend. Time has passed and still haven't got the gift set as promised when making the purchase. I've tried to call the store, I've tried to call mtn customer care, if even gone onto the website and filled in a complaint form online.... no response to the day... extremly disappointed in mtn for the bad service, also the cpa law protects us from things like this yet the sales consultant still went ahead with it.
