We booked via https://www.heathrowtaxi.net/ for a taxi to meet us at 8.30am at Heathrow and transport us to Gatwick. No sign of taxi driver so called to find out what was going on. Was told that the driver would be there about 9.30. Eventually he arrived at 10.20 so nearly 2 hours late. Before arriving the driver sent me several text messages which were obviously sent whilst driving. During our journey he continued to send text messages and as a result did not always stay in his lane of the M25. We had just left Heathrow and one of the texts was to his next client and he told him he would be there in 20 minutes, but we were about an hour from finishing our journey! In the end we were just glad to get out in one piece. We won't be using them again.
