You're insurance should have notfied you by phone call that they havent recived renal. TBF i would start to gather all the information you have as this could leed to a court case to where you could well be fined, and points, normaly 6 points.
How did you send your letter of renaul? i do hope signed for and have the recipt. In theroy its not your duty to contact the insurance company, they should contact you, they are the ones who are the worker and your the customer.
i can only see one way really. And thats to take out insurance before the date of the stop, you need to speak to your insurance as there is alot of loop holes with insurance companys, of course if you need some advice i would speak to a independant insurance company which is
www.needtoinsure.co.uk and ask to speak to paul Directly and expaine the problems and i hope he can help you with this problem.
By all means make sure you have things like recipts and when you sent them ect. as the postal strike is on they have a duty to tell you your insurance is no longer running, just like when they cancel a policy.
I would call Paul at needtoinsure and get some real advice from an insurance company, Paul is the owner of this insurance. maybe even take out a policy as he really is good.
Just refer my name RSTurboSI.
