Shell

I have been going to this store for 8 years. I have used a debit card to make transactions. when checking my bank statement I noticed there was (3) charges on the same date and same time.
I then started looking further and found numerous charges that I did not make. I then printed out my statements for the last two years and found 445 fraudulent charges.
I was getting charges on my card while I was working in another State. I contacted my bank and they agreed with the fraudulent charges. However they only refunded the last 60 days. I have $ 2, 448.68 dollars in fraudulent charges. I tried to resolve it with the owner of the store and was informed he could not help me.
I know I can't be the only person this has happened to.
I am going to take legal action.
Please advise or share your input. I also have statements from bank.
