McDonald dont sell what they advertise.

I decided to treat my family for ice cream today, and was really dissapointed with the service and exerience at McDonald's Pretoria North. I've ordered 3 caramel sundae's and 1 oreo mcflurry with extra oreo as this is our favourate deserts. To my suprise, when i received my order, the 3x caramel sundae's were half cups. I immediately asked the cashier as to why this is served as half cups because im use to getting a full cup of ice cream as advertised. She just told me that its the normal measurement and that they serve it like that. I told her that we bought ice cream regulary at McDonalds and never have I ever experienced this. She then responded again that, "these are the normal measurements". Clearly McDonalds are not selling what they advertise and this was really a dissapointment for my family. Day light *******. I really feel that the I did not receive the value for the money i paid!
