Disgustingly blatant dishonest service from Dawn Wing

I booked a collection for 18 July at 16:30. I was at the gate waiting by 16:35 and I had my phone in my hand ready to answer as soon as the call came in. The person called me at 16:37 and the phone rang for less than 3 seconds. As I was about to click on the answer button they dropped the phone. I immediately called the call centre and the agent I spoke to said unfortunately they cannot tell me who called as it is a call centre, it could have been anyone, but the person is still on the way. I waited an hour and no one came or called. I called this morning to find out what happened and the driver apparently left a note on my collection saying that I didn't answer. Clearly the person didn't want to make the collection and just buzzed me to make it seem like they tried to contact me. I am so appalled at this disgustingly blatant dishonesty!!!
