City Cabs (Edinburgh) Ltd 4+

I'd been using this app for a considerable time, with numerous favourite locations defined (which, incidentally, is a total pain to go through) when one booking failed to go through due to a network signal problem ... and ended up in the system in "an undefined state". This booking cannot be completed, can't be deleted, and City Cabs' only solution is "delete and reinstall" -- including copying in any saved favourites from scratch, by hand.

This just isn't acceptable. (On top: app not designed for use on large screen iPhones, e.g. iPhone 6+ or 7+, let alone ipad.) Switching to a rival booking firm's system.

This morning I was trying to get an Uber to work, Uber and bolt were taking a while to accept so I decided to try black cab, a bolt had accepted as the black cab was searching for a driver, I proceeded to cancel the black cab and as I was leaving my house to get my bolt a black cab pulled up but I didn’t think much of it. As I get in my Uber the black cab driver is honking his horn and shouting and I ignored it as I had cancelled the black cab, as I get in my Uber which he followed me too he started shouting at me and I told him I had cancelled it on the app, he became sarcastic and was still mad standing at my Uber. If I was not in a car I would have been more terrified, this man was in his late 40s early 50s and he is shouting at a 20 year old girl in the middle of the street at 8:30am. Not only is it embarrassing it was scary!

Booked a taxi to the airport the day before. On the morning of the booking the app said the taxi was 20 minutes away at the time they should have been picking me up.
I called the office who told me they were very busy and and I should have planned ahead for delays.
I have been travelling to London regularly 25 years so do not need to be patronised - a taxi booking service that allows you to pick a specific time should be reliable.
When the driver arrived he said he had only received the job at the time the booking was due and he lived 20 minutes away.
An unnecessarily stressful start to a long couple of days and I can’t help feeling that I was lied to by the helpdesk.
