A few recent (ish) experiences of mine:
My sister visited early November 2022 with my niece, on their last day we had a coffee in JL Oxford Street, nieces coat broke, wouldn't do up, so we bought a new one there and then.
Fast forward to April 2023, sister washes coat and the teeth of the zip come off. That was the third wash, in a high end washer on the right setting. Yet, when I contacted JL customer service, they made it out like it was my sister's fault. As the coat was bought in store, could I please bring it back to be assessed. Only after pointing out several times that the coat was in Germany did they finally give me a refund, but only at what it would be sold at this point which was £12.50.
Was in the market for a new suitcase, wanted something with good warranty and had intended to spend serious money on it, if needed.
Went to JL Oxoford Street, no help at all, went back a few days later, one guy from Briggs & Riley who was very helpful, but clearly working for his company. He told me that for most part of the day, there wasn't any JL staff in the luggage section, only people working for the various manufacturers. Bought a suitcase (B&R) elsewhere where the sales staff could talk me through the various brands and their pros and cons.
Again Oxford Street, needed a pair of black trousers for an interview as I've shrunken out of my good pair.
Chose a few went to the changing room, none fit quite right, so I gave up, came out of my cubicle and made to leave the changing area the way I came in when a voice behind me shouted "Ma'am, ma'am, OUT this way ONLY" from the other end of the changing room. My response was simply "Okay, but no need to be rude".
Good experience at Peter Jones, though. Still looking for black trousers I went there on Monday night. Staff very helpful and found me a really good pair. The changing room attendant had been working at JL for a long time and was close to retirement. She was honest with what looked good and what looked utterly rubbish on me.
JL need more people like her.
I shopped there a lot, both for myself and for my niece and nephew. There were times when half my suitcase would be full of children's clothes. Now, not so much anymore.
