My question is I am 3500 in debt because I lost my job and couldn't pay. I am working now but in collections for my accounts. I read online that if I pay the debt in full I can ask for a deletion of it on my credit. Is this true? Does it work or do they still pull tricks?

You can ask, they might even do it. Part of it is going to be who you talk with. If its outside collections, they do not have the power to remove items from your credit put on by the original lender.
