Used their click and collect service at Hampstead and they could not scan my order and had no back up protocol that allowed me to collect my goods. As a newly diagnosed diabetic I waited around and my blood sugar started dropping. When I told the staff member, he said I should have thought about that before I came in. I didn't expect to be waiting around in the store that long due to their technical issue. On leaving the store, he called me a fucking bitch. I wrote a complaint and they took forever to come back to me. They said the colleague handled himself well and there was no evidence that he did what he did despite my teenage daughter being present and hearing his abusive behaviour.
