Input: I accidentally left my keys in the cab and it was the biggest nightmare ever getting my keys back. I called the dispatcher and they refused to give me the drivers cell phone number and they told me they were going to call the driver and that ""If the driver has the keys he will bring them to me at the airport"". Finally after calling several people they told me that the driver said he found the keys and was returning them to the lost and found.

This is where the nightmare started. I called several times after that and spoke with several people to see if my keys were ever returned. I kept getting bounced around from person to person each person telling me when I described them that the keys were nowhere to be found. Finally somebody told me that they found my keys and were writing my name ""David"" on a sticky and putting them in a safe place. My fears were resolved.

I got back to Phoenix and they offered to drive the keys to me but in exchange I would have to pay the cab fare (which I had no problem doing). I agreed to this but first they made me fax all sorts of documents and pictures of my credit cards. This was a huge headache. When it was all done they told me a driver will be at my house within an hour with the keys. The driver finally shows up and it's the wrong keys!!!!

I called back Triple A and they refused to talk to me or answer any questions and were now very rude to me on the phone. I told them that I wanted to email them a picture of exactly what my keys looked like and if they could just go through again and match the picture with the keys, it would help me out knowing that they had my keys and I won't have to waste a bunch of money on a cab to drive out there. They refused and told me I would have to come myself.

I finally called up a different cab company (because they were rude to me on the phone, I wasn't going to give them any more of my business) and had Vip Taxi drive me out to Triple A Yellow Cab to go on the hunt for my keys.

I got to the Triple A Yellow cab and their lost and found was a complete mess. They had sunglasses, phones, keys, credit cards, and drivers licenses all in a big box. It took 15 minutes for one of the higher ups but he found my keys. Now why couldn't I have just emailed them my picture and they could have gone through the keys until they found mine?

This is what my mom calls ""Penny wise but pound foolish"". They might have thought I was wasting their time and that I spent enough of their time already thus they ended the call, but now they've lost a customer for life. Was it a good business move to blow me off and risk losing a customer?
