i went in to a tax service to see if i can qualify for a loan before tax season, i got denied. a representive there told me that i could still file somewhere else when it was tax time. so i did. i went to another tax service and fikled with them, while waiting for my return, they called me and told me that the irs said that i had already filed. now when i went to the first tax service, i did not consent for them to file my taxes, they dont even have my w2. what can i do? can i sue them?
