So glad you like the socks @faustina and belated Happy Birthday 🎉.
I am so sorry to hear about your horrid experience. I would definitely follow up your email complaint with Toast head office, unless you get a grovelling apology, preferably accompanied by a gift!
It’s an appalling way to treat anyone, much less a customer! My sister, (who also posts on here occasionally), has also had rudeness about mending, so they do have form.
(I had a bit of an unpleasant experience in the SM store myself last time, but that’s a different story.)
TBH, I have always been quietly surprised when people on here have praised the friendliness/helpfulness of Toast staff - it’s not always been my experience, sadly.
Please make sure that you do something lovely this week to try to make up for your birthday joy being interrupted x
