Had one good experience on a short journey, so booked a long distance trip through them.
Car never arrived. No answer on the taxi quoter phone number.
Phoned the cab company I was told I'd be driven by - they'd never heard of taxi quoter and couldn't do the trip.
Ended up stranded, having to call a mini cab and wait nearly an hour alone at midnight for a car company to send a driver as it was a busy night.
I called taxi quoter every day after until I got an answer, they said sorry and took my details for a refund that never arrived and have gone back to not answering calls.
DON'T USE TAXI QUOTER!
