I called Ic systems debt collection agency and paid off a medical bill for my youngest daughter and when i asked the lady i was speaking to on the phone if i had anything else in there system for me or my children she had told me that i have another bill for $50.00 and when I asked her if she could send me a letter so I could mail back a payment or call in the payment she told me that i would have to request a letter because they sent out a letter to me back in 2008 and I remember when i got the letter they put the letter to my daugher and when the called they called for her my daughter is now 4 years old. My husband and I told them that if they could send out a correct letter addressed to us or to the parents of my daughters name then we would pay it. She told me that we would have to request another letter and when i told her that we have since moved from the address that the last letter that was sent to there office in 2008 she refused to send one out is there anything that I can do to make sure that this does not effect my daughters credit, and is it even legal to put a collection letter addessed to someone under the age of 18 years of age. Also i though that collections have to send out another letter if you ask them to another address. I am just glad that they stoped calling me for now.
