awful service at Game Lakeside Mall

My partner had called Benedict from the appliance section at Game, Lakeside Mall. Benedict said to him if he came through immediately to purchase the fridge there would be no delivery charge (my home is 3km from the Mall). My son proceeded to do the same only to get there and to be told by Benedict and Rose there is a deliver charge and they were selling me a washing machine and not a fridge. After me speaking to the store manager and explaining the call to Benedict i was told to come back to the shop again to buy the fridge. A 2nd trip was then made to Game and this time Rose was rude and arrogant with my son calling my partner a **** etc. We have purchased many appliances previously from Game but the staff working there are unfriendly and rude especially Rose who at one time actually laughed and picked on me because i was in a wheelchair and looked down upon me like i was a nobody. Please can Game do something about this womans's attitude to other people.
