Select Home Warranty Denied Payment After an Approved Repair Mahwah New Jersey

Select Home Warranty assigned a roofing contractor to get my roof repaired. I did not hear from them for a day so decided to call and the owner of the roofing company said they do not service my area since they were located in a different town. I contacted Select Home Warranty and spoke with a rep name Earnest twice; he asked me to contact a roofer in my area and submit the estimate. I called and spoke with Earnest again and provided him the estimate. He asked me to get the repair done and submit the invoice for reimbursement; I requested Earnest to make sure he adds some good notes to the claim. Earnest typed in the note that he has authorized me to use my contractor to get the repair done; he read me back what he typed in. I got the repair completed and submitted the invoice for reimbursement.
I received an email today from Select Home Warranty that will not honor this claim since I used my own contractor without any authorization from Select Home Warranty.
