Paid for dishwasher installation through John Lewis but they refused at delivery to disconnect the plastic U pipe to gain access behind unit which should be a simple task for installers. I could tell the two guys didn’t want to install the machine as soon as they were in the kitchen, they were running late. On ordering I was only asked about dimensions and maximum distance of connections from machine in range of questions I had to answer. I would have assumed that gaining access would be typical for an installer… but not John Lewis! Had already had new washing machine installed by Appliances Direct last year who were really happy to do the job with no fuss whatsoever. I told the chaps to take the dishwasher away. It was the only obliging element of the (non) service.
