Still waiting for a refund on accidental charge!!!

Will never use Woodford again. The counter-service was great and the car provided was good. However their admin are useless; the service agent "accidently" charged two of my credit cards for the rental on collection on the 21st December and only acknowledged the mistake when I called them on the 28th December. Since then I have been promised a refund every day and am still waiting weeks later. I have now reported the issue to FNB as Woodford seem unwilling/unable to do the refund.
