I booked a transfer from my apartment in Streatham Hill to St Pancras on 9 Jun. 2 days before departure, I sent an email for confirmation, and the manager confirmed the transfer.
On the day itself, when no one turned up at the agreed time, I called their hotline. A man answered and couldn't find our booking, even though I gave him our booking number. He further said that the booking cannot have been accepted cos the company doesn't do city transfer!
It was frustrating and stressful to say the least, as we had to look for alternative at that early hour! Lucky we managed to find an alternative but at a higher rate.
Whatever it is, my advice is dont book from this website. Unreliable!
