Sentry Recovery and Collections Offensive language and Fradulent charges las vegas, Nevada

I received a phone call from this business on 3/27/2013 saying that I owed a bill to my apartments, which I was unaware of, once notified I was more than happy to pay right over the phone. The woman provided me with information stating my bill would be NO MORE than $419.36. The next day, I called after I looked at my bank statement noticing they charged an extra $20 fee, my charges were $439.36.
I called Sentry and spoke to a lady who told me that I was told there would be fees and I told her no I was not and in fact was in the company of two others who heard the phone call and never heard that either. She then changed her story and said that MY bank, Wells Fargo did it and I should call them. She was very very rude the entire time I spoke with her, telling me basically that I was a liar.
Then I called my bank, who said hands down they did not charge me and I filed a dispute with the charges with them right away on 3/28/2013. I called the business back and was directed to the same lady who then told me she never said anything about my bank, but that it was their bank that added the extra fees. I told her that I did not agree to paying any additional fees and that I will not pay it. She told me that I had no choice, I had to pay or they would sue me and put it on my
credit report and they also would give me more expensive fees, if I did not agree to keep the additional fee. I then hung up on her because of frustration of her constant attitude and talking over me.
I then called my father who is a financial adviser in NV and he told me to cancel my payment right away because this company has been known for their scams. I called to cancel my payment and was then transferred to a male. I told
the man that I would like to cancel the payment due to fraudulent charges. He said, "Fraudulent charges, how do you figure?". I then explained to him that the company charged me additional fees, without telling me and doing it on my card anyways, which is fraud because that is stealing money. The man then told me that I was indeed notified and that is not fraud. My boyfriend then asked me while I was on the phone, if I was talking to them again. I then replied to him and said yes with a bit of a laugh and the man from Sentry over the phone goes "Oh, you think this is ******* funny", and I replied with "Excuse me? Why are you being rude to me?" and he told me "because I don't want to hear your annoying laugh in my ear". I told the man to shove it where the sun does not shine and he replied with, "Oh, do you eat with that mouth too, you little S***". My boyfriend then grabbed the phone and said "Do not talk to my girlfriend like that" and the man from Sentry hung
up.
I immediately called the business back to complain and they sent me twice to voice-mail. Fifteen minutes later, I receive a call from the original woman I spoke to, who told me my bank charged the fees, and she said they would have to talk to their manager about waiving fees and that they would call me back. I did not receive a call all day and called again on 3/29/2013 at 2pm and the receptionist said that I was only allowed to talk to "Mrs. Shelton" and unfortunately she was out so I
need to try back. I then said I need to cancel my payment now and she said no I would have to talk to that person first. I hung up and called back ten minutes later saying I wanted to cancel it NOW and not later, she sent me to voice-mail again.
