Hello everyone,
Just a year ago, i received a bill from a hospital of about 51 dollars for some xrays they took of mine. i called the hospital to pay the bill and hence gave my credit card information to them. after about 15 days to 3 weeks, i received the same bill again. so i called them again to assure that i have paid the bill. they checked my file and told me that they have our credit card information and that i dont need to worry about the bill. after a month, i started getting calls from a collection agency regrading the same amount. i told them that i have already paid the bill and even filed a dispute. however apparently the case was still on file and in jan of 2009, they called again and left me a voice mail saying tht i still owe them the 51 dollars. so i told them that i have already paid the bill. they asked me to send them proof of payment. thats when i started looking for the transaction in my credit card statments and didnt find it. so i called them and made the payment. however, i realisedd that this is seen in my credit report and because of this, my credit score has gone down drastically. i have always had a clean history and have always taken every effort to keep a good credit score. i called the collection agency and the hospital to see if they can delete this of my credit report and they said, there is nothing they can do. is this true. is there anything i can do to delete this of my report. its really hurting me. please any help or advice in this matter will be highly highly appreciated.Thank you.
