On return from abroad we used the special phone at the airport but could not get through as the line was continually engaged. Eventually we decided to move to the collection point and use our mobile to try to contact them but the line was still engaged. We found later that this company had only one telephone line which was used for all bookings etc. and for all their other calls so the failure to get through was hardly surprising.
When we did get through, we were told that the coach was on the way, which was, in fact, a lie, as it still failed to turn up. When we phoned again, we were told it had been held up at the airport security barrier, which seemed strange as as the pick-up vehicles for all the other parking firms had come through without difficulty. When the coach did turn up eventually, we learned it had only left the base ten minutes earlier and had only been held up at the barrier for about five minutes.
We have used this company frequently in the past but shall certainly not be using it again.
