I will return the glasses and want nothing to do with a false advertising promotion

We decided to enter the Free Glassware promotion in store. For every R100.00 spent, you receive a stamp. These are then redeemed for the glasses. After spending more than R11000.00, we collected 60 and 50 stamps for the glasses we choose. To our utmost disgust and disappointment, we received only two glasses of each. Nowhere did it state that you only get two glasses for the stamps. After my mail to PnP, I received a call from Neran the store manager, only to be told that what we received was correct and that no one else complained. Well I think that this is High Way *******. I could have bought glasses from stores were by Icould have made my own choice and paid either the same or less for 6 of each of the glasses. The fact that I was told that these were from Germany, I still believe that I could do better. To spend R1100.00 and receive 4 glasses is a farce. If I had known that you only get two glasses for the amount of stamps collected, I would not have entered.
