Product: Debt collection

Now i received another letter, now is Encore collection company, this company sent a bill statement. I am dealing with this problem since two years ago, XXXX XXXX collecting was contacting me, now that I explained to XXXX XXXX collection, my bill was forwarded to Encore. I sent the bill as an attachment to consumer bureau email. My complaint sent to XXXX XXXX is not resolved. The dispute is not resolved since they are not removing the charges made by dentist XXXX from XXXX. XXXX XXXX said that they are trying to contact me but it is another lie since it is imposible to get on hold to somebody to talk to. Customer service always after made me explain the entire situation, transfer my call over and over. Today Monday, XX/XX/XXXX, i called them and i was transferred to XXXX different agents and after several minutes of explaining about the problem they transferred me to another and another without even saying why. XXXX XXXX just do n't want to do anything about the dispute. I had to contact the credit card bureau and that is why the financial charges were dismissed. However the main problem still exist because the original charges from XXXX still there, dentist XXXX is an arrogant person who broke a XXXX that did not need to be touch, it was a new XXXX, and he broke it with his tools while he was removing a XXXX, then i canceled the entire XXXX that was going to replace the XXXX, and XXXX refused to accept that. XXXX told me that i had to go in person made sign papework that he said was just stimates and refuse to refund what he already charged, XXXX, XXXX XXXX are on the side of dentist XXXX, because i was disputing the charges for already two years. I was physically abuse because he broke a XXXX without replacing it, scream and verbally assault me in his dental clinic by approaching to my face really close and yelled at me, saying a lot of offensive language, and saying accident happen. Accident happened but a dental professional need to be accountable for an accident or try to solve the problem or accept when a patience do n't want to be treated by him since his behavior is so violent. I was bully by XXXX XXXX and his staff. His administrator told me that I was going to model to XXXX. Make racist reference to my new dentist, and offensively spoke to me. XXXX offered to change the XXXX he broke but the enired deal was going to cost me another XXXX dollars, and i was afraid already and i just want it to run away from there. XXXX placed another XXXX, but that XXXX was already paid off by my XXXX, The main problem here, is that i cancel the crowns that it was going to replace the XXXX, that cost XXXX dollars. I canceled by phone and in person, and he refused to accept that. I never have the XXXX placed on me, and I do n't have the product on me. I can not solved this problem with XXXX XXXX because they are not taking me seriously. I just spend today hours of explaining and being transferring to deferents department, I just do n't want them to lie that XXXX XXXX are contacting to solve the problem, they are just ignore my dispute. I got a new bill from XXXX XXXX with the XXXX dollars and already charging more fees that came up to XXXX dollars. So it is a abuse after abuse first i have been abuse physically by being mistreated by a dentist who broke violently my dental crown, overcharging for a procedure he never did, verbally abuse me, and now XXXX XXXX are overcharging and refuse to dispute the overcharges that dentist XXXX made back in two years ago, XX/XX/XXXX. I am feeling unrightfully treated, abuse, and con and abused by dentist XXXX, and XXXX
