Disgusting service

I placed a door to door delivery only for them to deliver my order at a pick up point. They did not inform me they would be doing this and when I asked them the person I was speaking to called Millicwnt was absolutely rude. She was unapologetic and happy to tell me that they deal with a lot of customers that understand. I've never dealt with anyone more rude than this person. When I asked for a refund they tell me about 7 working days eventhough its their fault I did not receive my order
