disgusting service and dishonest

I WAS INVOLVED IN AN ACCIDENT ABOUT 3 YEARS AGO

WHEN I TOOK MY CAR IN TO GET NEW GLOBES FITTED AND TO HAVE THE LIGHTS ADJUSTED I GOT TOLD BY THE GUY AT THE WORKSHOP THAT HE CANT ADJUST THE ONE LIGHT COUSE ITS AN AFTERMARKET LIGHT

I FIND THIS VERY DISGUSTING OF DISCOVERY INSURE TO ALLOW THIS KIND OF THING

IF THE GUY NEVER ADVISED ME I WOULD NEVER HAD KNOWN

SO PEOPLE DONT UNSURE WITH DISCOVERY INSURE THEY ARE UNTRUSTWORTH AND VERY VERY DISHONEST
