In reply to Sam Edwards:
Don't worry about it. I called my prebooked taxi when I knew I was going to be late and the depot said they'll keep an eye on my flight number and send the taxi at the appropriate time, but I should call when I land to make sure.
Flight ended up being over 5 hrs late. We landed at 2 am. I called the company, who said they were sending someone over. I waited and waited for my bags to arrive only to find out that my bags had been lost. I got a call from the taxi driver saying he was waiting while I was trying to get my bags found. Somewhat curtly (my bad) I said, I'll be out in 10 minutes.
He started shouting at me and said I was black listed for wasting his time and he was off.
When I finally sorted out my bag situation I called the taxi depot, who just sent another taxi.
Long story short; don't worry about it.
