Esurance Approved $448 for insurance rate took out $908 without my approval Nationwide

Scammed by Esurance. I was promised a rate of $448 and after I gave my bank information over $900 was taken out due to a "discrepancy". I cancelled the policy of course but then during communication with a different rep she advised me to re-open the policy and they would in fact honor the rate given since I was misinformed by the first rep. This was all verified via recorded calls. I was told the funds would be back into my checking account 5/9 or 5/10 at the latest- also on a recorded call. I cancelled my current provider Monday. Today I get a call the request was denied, even after admitting fault, and they still have my $908 from my account that they were never authorized to take out. Completely overdrew my account and I have no idea when I will get my money back.
