United Collection Bureau Double dipping in my account. Toldeo Ohio

I tried to contact UCB and was trying to explain to them that they double charges my bank account twice. I was told that they only have one charge and the other was the banks problem. I called the bank and was told that they did draft two payments and I needed to contact them and have them refund the second charge. I called back and was told that I was an idiot and so was my bank. I tried to reason with the lady and was hung up on. I tried to call back immediately and did not get a response. I called my bank back and told them that they (Collection Company) were telling me that it was the bank fault. The bank said it was not they had two separate transactions. I called the collection company back a second time and talked to a gentleman that was nice at first and I explained the situation and he said that I was mistaken and I must be stupid since I can't read my bank account statement. I explained to him that I had two copies of the check and they were both identical, he then said that if the check were the same they were not the same. I tried to explain to him again, but he cut me off and told me I was a idiot again. I asked for his supervisor and he told me that he was not going to give me that info. And he said I could fax the copies and it could take some days to investigate. I them asked him if they could not draft from my account again, since this was the second time they have done this two me. I was told no and that was that. I asked him for his supervisor name again, he became rude and disrespectful. I tried to talk to him and he continued to interrupt me. I finally asked for the fax number and he said that he was not going to give it to me since he did not want to help me. He did not care what happened. I asked for his fax number again and he said I will not give me his fax number he will make sure nobody helps me. I demanded the number again, in the middle of my demand he blurted out a number and I was not able to understand and was hung up on.
I called back my bank and asked if there was anything I could do about this situation. I was told that I could put a stop payment on the company and the amount so it would never draft again. It was best to change my account number. The bank is researching it as possible fraud.
