Went to the post office today to tax my car but was embarrassed to find I've had the wrong insurance certificate since last December When I bought my car new last October, it replaced my written off 156 and due to the postal strike at the time the car went on new plates for 4 days before I could get my private plate transferred over. CKI did everything right but on renewal the issued me a certificate for the original reg number. Foolishly I didn't check Anyway, called them at 16:45 and they admitted their mistake, confirmed I was insured and promised to send the propper cert out 1st class. What happens if it doesn't come? My car will technically be un-taxed from midnight tomorrow What shall / can I do Cheers, Simon.
