Misleading Adverting...

Misleading Adverting on Checkers60 App - They advertised Nescafe cappuccino at 3 and pay for 2... We ordered 2x Quantity twice (2 different types) Yet they send us none of the 3 boxes??? When queried we were told if you come to the store pick 3 and only pay for 2.... But tied to tell us to go to the store to sort it out???? Why the hell would I then order 60/60... Disgusting!!! Don't order this supposed Special... It's Misleading the customers.
