Poor service at King Price Licensing department

It looks like i have ran out of patience with KP insurance. I have been asking them to deregister the vehicle that was written off on the 08th of January 2021 under my name , they kept promising 5 days . I cant recieve my current Vehicles license disc And its hard to make calls as a disable person(deaf) i need to ask a friend to make calls for me King Price is also aware of my problem . i also tried to send them emails and they dont even bother replying to my emails
