Not accepting legal documents

A lady drove into me. She said we must contact her insurance to log a claim ourselves. That we did. They wanted a booklet of documents. We produced all legal and original documents. Including a NO CLAIM LETTER FROM MY HOLLARD INSURANCE COMPANY. I WORK FOR Telkom AND AS A PERK WE GET VEHICLE INSURANCE FROM THEM. SO ON MY NO CLAIM LETTER FROM HOLLARD THERE IS THE TELKOM LOGO AS WELL. NOW AUTO & GENERAL IS NOT WILLING TO PAY FOR THE DAMAGE TO MY VEHICLE BECAUSE OUR NO CLAIM LETTTER FROM HOLLAND HAS THE TELKOM LOGO ON. IT IS A ORIGINAL AND ALL INFO ON IT CAN BE CHECKED BY ANY LAWYER OR LEGAL DEPARTMENT AS THE ORIGINAL.
