We made our first ever claim with the government this move. The movers smashed the cornor of my table,it will have to be replaced. I didn't think I had the receipt and I told them the wrong amount for the table and chairs. They ask for a comparable value online, in my haste to get it done and with all the confusion with Terry leaving I sent the wrong one. When I called and asked the amount and found it somewhat lower than what I was expecting I complained. I called back three times to talk to the lady and she wasn't happy, in fact by the end she was rude.
I decided that day to check the one box in the basement that said paperwork, just hoping I had the receipts from 2002. After digging I did find the envelop that said 2002 receipts, and inside there it was. I realized I was very wrong on what we paid. I got the woman's email and sent her that and a picture of my table to show her it wasn't the one she was thinking. I sent it Monday and on Thursday I emailed her asking if she had gotten it. She wrote back and said something to the effect that I sent something in, they paid it, if it is wrong it is my fault. So I fired off another email saying all I wanted is what I paid for it. I get an email from her boss that they can't give more than what was originally claimed or they can get in trouble and get fined.
I send another email saying how unhappy I am with their company and how I think they no my table is worth more, but are capitalizing on my mistake and how that says so much about their company and employees. I also ended with that I would tell everyone including my transportation office how they handled my claim, and that I would be sure to write a letter to their customer service office about their rude employees.

A little later I get an email back saying they will review my claim on Monday.

Point of the story. I made a mistake, take your time with claims, but also be forceful, don't just give up when someone says no. I don't know if I will get anything more back, but I made my point.
