7 wings for R60

I called mr delivery on 01/08/2015 and ask to place an order at spur for a half portion of buffalo wings and a lemon twist...when they arrived i discovered that there is only 7 wings in it..when you order at spur you get say 15 wings but why not if you order from your home..im dissapointed in how much you get...R60 for 7 wings unbelievable...
