I went to a chiropractor to get an adjustment. It was the first time I had seen this doctor based on a recommendation. After he adjusted my shoulders only, I was in pain for a week. I disputed his charges and his treatment. I ultimately owed $60 and for a while I refused to pay. Once it went to a collection agency I decided I should pay the bill because I didn't want it to negatively effect my credit report. The collection agency was trying to charge me $110 when the bill was only $60. I payed the $60 that I owed and that was it. There is now a $50 non payment on my credit report. I contacted the collection agency and they stated that they sent me a letter stating that I would have to pay all related charges for them to collect the debt. Is this legal? I don't see how I would owe $50 more than what the bill actually was. Any advice.
