Emerald Mini Cabs in London

Ridiculous excuse of a mini can service! I once used to the service to get home and the driver, who was quite a nice guy offered me a few cards in hope that the company I work for would use them as their regular cab. The following day I decided to give them another go. Running late for work, I decided to call for a cab to meet me at a local post office. The controller told me there would be no problem and the cab would arrive shortly. After about 10 minutes the controller called to say that the cab was only 10 minutes away and I should wait by the post office. Despite the cold and rain I decided to wait. When the ten minutes was up the controller called again to let me know that the driver had now decided he couldn't come to collect me because they'd had an occasion where they've probably taken too long and the customer had left. Furious, cold and now definatley late for work I asked what they could do to fix the problem. Apparently all the could do was apologise and offer a cab to pick me up from my house in half an hour. Shameful service from the members of staff and I would definitely advise anyone thinking of using this cab office to not waste their time or money.
