Still waiting on refund

Overall reasonable value for money. Have rented previously with no issues. On last rental side swiped by bus while stationary. As only rear damage did not have to hand vehicle in immediately. When I did return made sure I completed the incident form in full. Rather irritating employee insisting he would fill in all the details after me, but I made sure he signed it and it was completed and I copied it before leaving. Also got the details for reference number and who to email before leaving. Now out of country and they can't find reference that they gave me. No word on my deposit refund yet, although I got a prompt email to say agreement was closed. I got offered 5% voucher off future rental no matter what review I leave but I don't think I'll be using woodford again.
