Slough Taxis - United Kingdom

SLOUGH ******** AVOID ! I called and asked for the taxi in 15min, I asked if this is enough time for them. They said YES. I called 17min later the same guy said it was too short notice and he needs 2-3min. I called 10min later and no one picked up the call. I had to call competitors and no problems at all.... so AVOID !!!!!!!! AVOID !!
I would not be angry if at the begging guy would tell me "listen, I might not be able to help you etc".
