My depth sensor needs to be replaced and I purchased my computer in Feb 07 at an authorized aqualung seller. I'm aware that I am still under the pro-rated extended warranty. However, the only receipt I have isn't itemized and only has the date of sale, shop's name, and the amount I paid. I can't get in contact with the shop or it's owner because they went out of business and the phone numbers I have for the shop and the owner are all disconnected. It has also been pointed out to me that when the serial number is searched in the aqualung database, that there is no record that it was registered through that shop to be sold. This has become a doubly wammy and I would like to give my shop the benefit of the doubt and that there might have been a mix up but I'm also concerned and was cheated out of my money since I was told I was purchasing a new computer and paid for a new Suunto Cobra. If anyone could help or give advice or anything I would appreciate it. I know it looks like I'm SOL but if I can get to the bottom if this and see where the mistake happened or even if it can be fixed would be great.
