Wimping about Wimpy

Purhased 2 Wimpy Burger meals today to be delivered. Ordered 2 cokes as well at 20.90 each. Upon sdelivery i find out that the coodrink came in cups. 2 Cups cost me 41.80. Crazy man - could have purchased myself two 2 litres for that price.i ordered via MrD and nowhere did it state i am ordering cups and not bottles. i really am not impressed. I am a very loyal Wimpy supporter and i am on a first name basis with your Canal Walk staff. i want to know what you are going to do to remedy the situation.
