Hello, OP here with a rundown of what has happened. I called Princess again Friday and was again told I was a new passenger and no evidence of anything else, even with me having the same phone number for many years and I gave the other email address that it could have been under. The new travel agent told me again Princess purges every 10 years. I messaged my original TA and she never replied, presumably because I booked with a different TA. So I read through the above thread in more detail and took the advice of whomever suggested trying to input my old email address to find another online account. Bingo, reset my password, signed in and got my original reward number. Chat this morning got me nowhere, so I called the 800-901-1172 suggested above and he was able to merge the accounts. What should have been so simple became soooo irritating, basic customer service is a lost art! Thank you all!
