Insurance claim declined unfairly

Good morning I wrote my review here because I couldn't find the right platform to complain about Affinity whe coming to covering cars. My car was involved in an accident driven by my husband whom I nominated as a driver which they do acknowledge now Affinity declined my claim because I they say i did not send my husband ID and license of which I did they say I must provide proof that I did send them where will I get information of 2019 bare in mind I am an old person I send those documents at an internet Cafe just like the accident report I used an internet Cafe...Affinity have been deducting money for almost 3years I haven't defaulted on my car premiums how to you start deducting money and when you need to cover a client you come with such pity stories what must I do with the car because they say it's a write off Affinity is a ****
