Product: Debt collection

I was first contacted by Berman & Rabin on XX/XX/2022. I did not recognize the number and I let it go to voicemail. Not only did they not leave a voicemail, but they contacted me two more times on XX/XX/2022. They made no effort to leave a voicemail either of times and I have not received any written notice from them. I was contacted by a previous debt collection agency, in which I spoke to a lady who tried to have me pay this debt without even confirming it. I had let her know I do not have any debt, nor did I sign a contract with XXXX XXXX, the company who claims I owe them money. No procedures or work was done and I was charged for the consult that day, which I have an online payment on my credit card for. I never received any bill from XXXX XXXX and out of nowhere I am in collections. I was harassed by XXXX XXXX to go back to get work done, but I had gotten insurance and was way better off, considering their pricing was ridiculous. Now, I was in shock when I received a collections letter for roughly {$1300.00} from the first debt collection agency. I tried to have them email me this contract XXXX XXXXl said I signed & they never did. Instead, they sold this debt to Berman & Rabin, who have called me on two separate numbers, and B & R has yet to send me any written notice. The only thing I ever signed for XXXX XXXX was for a tech named XXXX XXXX XXXX XXXX who told me I had to sign these papers that informed me of pricing if I WERE to get dental treatment, which totaled to over {$5000.00}. I even asked her if it was a contract because I wasnt sure I wanted to proceed with anything and she told me it wasnt, it was so they knew she made me aware of my options. There was no contract, no date. So I am confused as to where they even got this ridiculous number of {$1300.00} or whatever the specific amount is, if the only paper i signed was for well over {$5000.00} to let me know how much all the work I needed costs. Scam only word I can think of just to get money from me. I cancelled my next appointment because I didnt want services with them and XXXX told me to call back if I changed my mind. I obviously did not, but kept receiving calls from XXXX XXXX At least 2 a day. I want this fake debt to stop. I never once went in for treatment. I went in for a XXXX in which they did free XXXX because I was a first time client and a free XXXX for the same reason. If they had done more work on me they would have charged me that day before leaving. I made an appointment for a XXXX XXXX, paid a deposit in which I was told if I canceled I wouldnt get back. I did cancel and did not care that I didnt get that down payment back because I wouldve rather lost that money than pay the rest of the money. There was no work done for me. I was XXXX XXXXXXXX that I paid for myself out of pocket at a XXXX XXXX. It seems very shady and dishonest for XXXX XXXXXXXX to send me to collections in the first place but then when I try to fight the first collections agency, they decide to sell that debt to another one who hasnt even tried to really contact me or send me this proof of debt? Disgusting measures being taken by crooked debt collection agencies that only affect me.
