DentalWorks Southpoint

They sold me to a collection agency, shame!Just got off phone with the collection agency DentalWorks sold me to. I was there in December for my crown treatment. I paid my portion of the bill while they were supposed to claim the rest of the amount from my insurance company. They forgot to do that. I got a letter in April saying that I owe them over $600. I called them up and they admitted that its their mistake. They promised me that they will correct it soon and submit a claim to my insurance company.They also requested me to ignore the bill. I did. After a month, I got a letter from a collection agency based in Ohio asking me to pay the amount over $600. They have my social, my home address, phone number and all the details. Dentalworks sold them all that information without talking to me or without looking into their own records. I built my credit history over decades. One bad tooth and all my effort has gone waste. Thank you Dentalworks! I am definitely not going there again.Desired SettlementA letter stating that all my information they have sold to the collection agency has been removed and I owe nothing to the collection agency. A Guarantee that the collection agency will not put any negative charges on my credit history.
