Bad service

My father bought some groceries at Schenk and it supposed to be delivered today but they didn't. They delivered to a guy that stays in the open space next to my father's place. I called them at 16:08 and the lady promised to check the order. The lady that answered the phone hang up on me while I was talking to her. I called again at 17:00 and I was told they couldn't read the name on the list which is not my father's problem because its one of their employees who wrote. She told me they will only deliver tomorrow which was unacceptable. She appologised but you can hear that she is not feeling sorry for him. She again hang up on me. My father has no grocery today that's why he was there early today. I don't accept they customer service at all. I have to buy him something to eat today. I'm so furious because they don't customers with respect. They don't stay far from my father's place, they can dropped them when they knock off but they didn't because they don't care at all. The store is at Van Riebeeck street in Maclear, their number 0459321099. My contact number is 0817302641 or 0606677410.
