Belmont Petroleum Corp. Carson Petroleum Company Unlawfully made multiple unauthorized withdraws on my credit card. Lansing Ohio

 It all began when I ordered home heating fuel through there app. (it has since been redesigned to be more accurate after I brought it to their attention.) Firstly, I ordered the fuel by filling out the form online. I ordered 150 gallons. When they delivered, I was not home and they left me a bill for almost $1200.00. I immediately called about it. I was told that I had ordered 500 gallons. Much to my surprise, I completely disagreed and told them no, the form that I filled out was completed accurately. They got the 500 mixed up with my tank size. But, they preceded to tell me not to worry about it, because I can make payments as long as needed. And, they would be more than willing to "work with me". There wasn't anything I could do at that point. So I made $300 payments at a time to them. I missed a payment, and called them to make a partial payment over the phone because I had to use two separate accounts to do so. After I gave him permission to withdraw $200.00 from my bank card. And asked them to give me a few days till my check to deposit to pay them the rest. He agreed but in the process, he withdrew $700.00 from the account I authorized to use for the amount of $200.00 only. This was all while I was driving my car, and going to work. I then had to call my bank and file a fraudulent purchase on my card. Close that account, and order a new card. In the meantime, he also accessed my second card for an unauthorized amount and transaction. After I called them about it, he told me they were going to call the police and sue me for the balance. They never did do any such thing, except send me a letter from their company and adding on over $700.00 in some kind of unjustified legal fees. And, just two weeks ago, they made yet another transaction without having any contact with me or no approval at at. They made a random withdraw of $50.00. I had to call that establishment as well and cancel that card and wait for a new card to arrive 10-14 days later. I again, had to file a fraudulent claim. How can this be legal?
