We sold the property covered by Wright Flood, a check was issued to us for the remailing portion that we paid, we deposited the check, Wright canceled the check, saying it was not the correct amount & the bank charged us a $12. cancelation fee, Wright then sent us another check..... I have been on the phone with Wright Ins numerous times to get them to pay the $12. fee & continue to be told it hasn't been been approved.... What do I have to do to get you to send me the $12. I was charged because of your error???
