I feel like there are a TON of glitches when buying hair and some are really weird (like some people get displayed wrong prices for whatever reason).
Your logs are also not making any sense at all.

According to this you bought the hair 3 tims, but once for 350 Food and two times for 175 Food.
I have refunded you the extra 350, but at this point I start to feel like starkad will have to completey re-write the Cutting Crew system since he can't seem to find the source of all the errors otherwise and that will probably take years a while.

Ooh, I KNEW I clicked that button three times! I doubted myself after looking at the FP difference but I knew I clicked it three times. I think I was charged half-price for the second and third times because I think the system thought I was changing the hair colour but keeping the same style.

Thank you for the refund!

I had a similar issue, after clicking "confirm" the message did not change but I did get my hair though.
