Let down by hair and make up artist!

Hi everyone,
I’ve got a dilemma with the hair and make up artist that i booked.
I paid a deposit and had a hair and make up trial (included one style of make up and hair) then was told i need to go and buy hair extensions and to contact her when they arrive. They arrived and i messaged her but got no response. She replied the following day offering me a day the following week which i accepted and i asked for a time as it was 4 days before the wedding (i have a lot to do!!). She didn’t respond so i messaged and called. Eventually she said she was with a bride and would contact me later…..she never did! That was over a week ago! Today is supposed to be my second hair trial and despite calling and messaging on both wattsapp and imessage (basically begging her to give me a time) there’s still no response!With only 4 days to go until the big day i have had to make the decision to book someone else. I have paid a deposit and paid for the hair and make up trial.Do you all think i have the right to ask for my money back?
