I need to figure out what's going to happen here, so any advice is appreciated. Here's what happened so far: Yesterday, I check the mail and there's a letter from UPS (who I don't use for shipping). I open it, and its not just an invoice, its a collections notice. For $22. Apparently someone used my account number from many eons to ship something (my # is the same number over and over with a "W" in it, so its very possible someone just guessed it). The account is super old, so it had my old phone number and expired credit card on it. This is why they couldn't charge it, and apparently why they couldn't reach me - which is bogus, because the collections notice made it to my house, why couldn't a notification? I called the number on the slip yesterday and nobody would talk to me today. It took 3 tries today, but I finally got through. She figured out what it was for (I didn't recognize it) and I said I'm not going to **** around, its $20, here's my credit card. She processed the payment then and there. She said she would send the invoice to my house so that I can dispute the charge and get my money back... I'm not holding my breath. But what does this mean? If they sent it to "collections" as the letter stated, will this show up on my credit score? Will I have to fight it? Help!
