I went to the hospital before I joined the XXXX, I could not afford to pay the bill. I enlisted in the XXXX and was contacted by XXXX XXXX XXXX for the hospital bill, I paid this collection company the entire amount {$1000.00}. I discovered that another collection company First Source Advantage is collecting the same debt. I have contacted them and they said it is a different bill for a different collection. I disputed with XXXX and they said I did not pay this debt. 
I did some research and found that the hospital I went to XXXX XXXX XXXX was purchased the same month my debt went into collection by the TN XXXX XXXX XXXX which was XXXX 2013. I paid the collection from the TN regional health system but the collection from XXXX XXXX XXXX which is First Source Advantage will not accept this explanation and says they are XXXX different hospitals. I look online today and they have the same address, phone and website for TN XXXX XXXX XXXX. 
Please help me get the collection removed from my report. Please let me know if you need any other information..
