He then proceeded to drive the whole way to our house whilst either on the phone. At his ear with one hand. And also texting away whilst driving.
I think the above is bullshi* and comes from a woman with a hyperactive imagination.

Who the fu*k sits in a taxi with the driver talking and texting on the phone for the entirety of the journey and says nothing?
It is obviously something that has upset her enough to cause her to question/complain about the driver.
Let us face facts; their are drivers out there as described and it does not mean that she is wrong. As for her thoughts/attitude! Not everyone is 6'0" tall and weighing in at 15/16 stone, neither are they fighters or confrontational, they may be timid/fearful.................but it does not make them wrong.
As Foxtrot says register a complaint with the L.A, do not do it by telephone or email, as it can and might possibly get lost. If you are sincerely worried, then send a letter in a proper manner by outlining everything that happened - stick to the facts i.e nothing overly personal. Just to confirm that you mean business, send it by recorded delivery, it will cost you around £1.72p.
