This Complaint has been filed about Bank of America and their practices when it comes to fraudulent charges. Bank of America states on their website if you report fraudulent charges as soon as theyre withdrawn they will be covered. You will get a provisional credit and then they will investigate. Not only did they not give me any money back from fraudulent charges but they closed the claim and are refusing to pay. They are claiming I authorized them with a PIN number used for purchase in person but the charges were in XXXX XXXX I live in Pennsylvania and Ive never been to XXXX XXXX.Every time I call I get a different answer from them. Now they put a - {$880000.00} withdrawal on my account Bank of America is refusing to pay a fraudulent claim. Their practices are unethical and probably illegal. They have put {$880000.00} withdrawal on my account.. When I call they didnt admit to them doing it. They denied the claim with clearly fraudulent charges that were done in XXXX XXXX while Im all the way on the other side of the country in Pennsylvania. They claim I used my pin number for the purchases. Now I had it happen for a second time same thing in XXXX XXXX and the claim was just submitted today but one banker already admitted to me that they have it listed as authorized. 

Starting on XX/XX/2020 charges adding up to {$1200.00} that are fraudulent charges were submitted to Bank of America after they alerted me a fraudulent activity on my account.After some time I went to check my claim and it was listed as closed not paid. When I contacted them to discuss the matter they told me that they were authorized transactions. They claimed that a pin number was used to make these purchases. Originally telling me the purchases were made Via Internet because I asked them how it would be possible for me to go from XXXX to Pennsylvania overnight when I never left my house. Then backpedaling three days later an employee told me that they were made in person With a pin number. Now how can one purchase be made in two different ways? So I called them back once I gather some data and told them I know they were made online because I called and acted like I didnt know the claim was closed and that employee told me they were online purchases. Jumping forward to the date of XX/XX/2020 my account was once again and promised and this time in the amount of {$1100.00}. I set up so any purchase is made online will alert me immediately according to their application. A delay of XXXX hours from the time the purchase was made to the time I was alerted of the purchase caused the amount above to be removed from my account before I can stop it. Purchases are to this day still pending but they are telling me that they can not give me the money because the merchant already took it but they have not even been processed from Bank of America yet. Their policy at Bank of America is to give a provisionary credit right away and then investigate the claim and if it is found non-fraudulent then they take the money back. I to this day have not received any money from the first clean let alone the second one. Now my account is - {$880000.00} overdrawn by Bank of America. Tell me how that is a practical procedure for banking to use. If this doesnt get resolved can you imagine the impact on my life my children my great grand children will suffer from this as I have two accounts open with them and my savings account is also - {$880000.00}. Please help me I have been on a stay at home order from the state of Pennsylvania since The beginning of XXXX. And both times I got money from our US government it was taken out of my account that I hold with Bank of America and refuse to be paid back starting to see a pattern here are you?
