False advertising

So we visited Swaadisht Northgate Today and we were disappointed in the manner we were treated.

We spend more than R250 in store and as per their website it should come with 8 free wings. When we enquired about this a staff member Emon didn't want to help us. I went to the Manager Forhad and he didn't want to hear anything, nor could he give me a chance to talk all he had to say it was head office problem and we must phone them.
