Asda Lavender Hill, Clapham. I booked a time slot for grocery collection between 1-1.30pm. My groceries were not ready by 1.45 so I arranged to come back after my meeting that finished at 3. I got there at 3.15ish, called collection and told them I had arrived. 10-15 minutes later the worker Peter, sauntered down. I told him how long I had been waiting, he said it's not his fault. I said an apology would suffice. He said he's not apologising. Peter said if I kept taking he couldn't give me my groceries. I said that he was basically telling me to shut up. He then came out with my groceries, I opened my boot, he plonked them on the floor, didn't ask for ID, and walked off. Asda did not take my account of what happened into consideration.customer service was awful. Peter said he does not represent Asda. I will never use any Asda stores again and am very very disappointed.
