NO DELIVERY OF ITEMS PROMISED

I have been requesting a IBT from Sportscene in Gateway for going on two months now, at first i could not get a hold of the store for more than a week (they were the only ones in SA that had stock) when i finally got hold of Sadik at the branch i was promised that the item would be sent the next day and to not worry two weeks later still no update or item i find out that the item was sold to someone else and when we called him back he said he had no clue what i was talking about i did not speak to him. Yet i had his cell number that i was calling on. The second IBT was simply not set and was held back at the store for a customer (THE CUSTOMER WAS ME) the third one I was given a ram way bill number and everything and promised it was sent, i gave them a week and nothing turned up only to now be told they sorry the shoe was sold the same day to someone else ON A LAYBYE and i cant have it!

Which means they have the item and are giving it to someone else who has not even paid for it yet! Every time i call i get told to not worry someone will call me back but nothing happens. I have dealt with managers, their twitter account and their call center and yet no one has called me back and i am no closer in getting my item because now they dont have stock (they still however have the laybye for the person that came after me and has not paid for it) When i started calling they had 6 at that branch.

Yet i am not sorry there is nothing they can do like how is this acceptable service? Do they just want me to go away and keep quiet??
