lack of service

I did some shopping at The Checkers Hyper in Blue Route, which included a bottle if Milkshake for my daughter. when we arrived home, she un*****ed the top only to find that the foil under the top had two holes in it and that the bottle was not full. I called the store and was put through to customer service. the person on the other end could not help me and said that she would put me through to the manager. I was put through and waited for 10 minutes for someone to answer, untill the call was ended.
