Insurance Advice ?

Hey Guys

Just wondering would anyone have advice for me , I cancelled my policy with the AA back in March and have now recently gained another policy with a different company who are requesting my no claims bonus certificate .

AA assured me it would be back to me in 7 - 10 days , 2 weeks later , multiple emails and a complaint they keep extending the dead line saying it is the underwriter who has not provided it and it is out of their hands .

Feeling a bit stuck because I now have a policy I paid for but no disc as a result of AA inaction .

Got no where with my complaint and have already been onto the FSPO who advice is to go through the complaints procedure ? I’m now at risk of losing my insurance policy because I haven’t provided the appropriate documentation , kind of left in limbo and feel like I’m being held hostage by the AA.
