Sadly, this is true. Sad because the companies do such practice and sad because people are too ignorant or lazy to do anything about it or even check in the first place.
In my case, I was surprised to find that even the credit reporting agency Equifax was not on the ball after being sent several registered letters. Took quite some time just to fix a couple mistakes.
Having said that, you need to research the law in your area. In some cases, you can get rid of collectors in certain ways. In other cases, collectors keep harassing you regardless of the validity of the debt. In yet other cases, one collection agency will simply "sell the debt" to another agency and it continues like this over and over.
IMO the best course of action is to calculate what you feel is the correct amount that you owe in all fairness, and come to an agreement with whoever is currently holding the debt.
BEFORE paying:
- Verify with the original company that the debt is clear with them. IF not, then you should be able to pay them directly instead...
- Verify the collection agency is licensed to collect in your area and is legit
- Negotiate until both parties agree on the amount.
I've had bad experiences with phone companies and ended up getting some bills that made me go WTF; regardless they sent it to collections. In the end, I only paid a portion of it and the case is closed. I still ended up paying more than I thought I should, but a lot less than they were originally asking for. All my registered letters to the original company were completely ignored.
