UNACCEPTABLE UNPROFESSIONAL SERVICE

Placed an order, driver says he's arrived, I must come to the Main Gate to pick up my order, I say come to my door, he says he will get lost, I tell him to ask Security for directions. I'm a pensioner with limited mobility and no way of getting to the Main Gate which is about 500 meters from my house. Plus the reason why I order for delivery is because it's delivered to my door. I phoned Security at the Main Gate, no, no one is here! So where is my order??? This is totally unacceptable
