count wings

I travel a lot between Pretoria and Durban and I always stop at Montrose KFC and buy my favourite wings and always buy 8 in da packet but it happens now for the 3rd time to only get 7 wings in da packet. I used to travel with the bus so I don't check whilst there cos we rushing but today I also bought it when I'm in da car and eating only to find 7 wings instead of 8. Please I understand you work under pressure but try guys and give us what we paid for.
