Devastating loss and kind gesture

My little Yorkie. Bella had difficulty breathing on Tuesday evening. She had been on chronic treatment for a trachea problem so we booked a vet visit the following day. As normal our card was loaded for a vet visit and and off we went. The news was devastating she had a growth on her heart and her lung capacity had been severely reduced. There were also several other indication on the X-ray of additional growths. The vet informed us that our sweet Bella was suffering and we reluctantly decided to follow their recommendation. After we said our goodbyes we paid for the visit but the amount exceeded the allowed visit fees and i paid the rest out of pocket. We submitted the invoice and proof of payment as required and thought the matter was finalized. We then received an e-mail from One Plan that the matter would be referred to the committee, we had no clue why. The next day we received another e-mail informing us that the extra payment i had made would be refunded by One Plan. This was not expected or requested. Thank you for your kind gesture we appreciate your empathy and this is why we have been clients for as long as we have.
