Yes you can dispute Debit Card purchases, take all the information to your bank, they have a dispute ach form. They will charge back that amount to the vendors account and issue you a credit. You can also contact your local Police dept, and report the fraud and secure a police report from them and take to bank. When you go to the bank, take all phone numbers, a list of how many time and how you tried to contacted them.
