Upgarde of contract but no phone

I upgraded my contract at the 8ta store in Pavilion on the 18th of April. I had upgraded to the Samsung S6, but was told there was no stock and as soon as the store receives stock they will inform me. I had called the store today over 2 weekes later only to find out that stock had come in last wek but I was not issued to me neither did they call. They have issued to other people but not me. Now I have to wait a further period to get stock. I had called the store on numerous occasions to enquire on my phone.<br> Poor service from the 8ta store. I even contacted the manager Vernon on 22 April but no joy.
