Hi guys need some advise did a customer back in 2020 in July. She wanted ash hair I’d did tell her it take tome to build up to the Color. Anyway she decided it was to gold she she came back had a toner on then she said it was to ash. So she came back for a third visit and had it broken up with some dark blondes ect. She was really happy then a week later a receive a message saying she wants a full refund and for me to pay for her hair done before done else where. So as a good will gesture I did refund her.... then I later received a message in September asking for my insurance details was 9.00pm on the night so I blocked her as far as I was concerned there was nothing wrong with her hair and she has a full refund. I’ve now today in March 2021 has a letter arrive asking for my insurance details again. Otherwise she would seek advise. Has anyone and anything like this before
