Refund dispute

LaurenCarderFox

Hi! I’m a musician and singer, and have been using the thumbtack app for about three months now. I am a guitarist and I had a couple reach out to me several weeks back to play violin for their event. Although, on my website, it only says that I play guitar. I have tried multiple times to ask a refund for the lead cost and it has been disputed every time. I don’t understand why. This is like someone asking a plumber to do an electrician job. Can someone please help me understand this? Is there anyone else I can talk to?
