THANKS TO ASDA CAR INSURANCE IM NOW FACING A BAN!!!!

I having already a non insurance and 6 points on my license due to no fault of my own, I took out a policy with asda I've had a license for 22 years but always been a named driver on my father's policy, after my dad passed away last year I had to basically start from scratch and a a cost of £104 per month.
bearing in mind I've not once missed or made any payments late.
so the last payment was taken from me at the end of December 2015 approx 1 week ago.
Today I was stopped by the police as it was showing that I wasn't insured and given a producer to take my insurance documents within 7 days, NOT A PROBLEM I SAID AND NEVER ONCE EVEN QUESTIONED THAT I INFACT WASNT INSURED until I got home and rang to find out why it showed to police that there was no valid insurance.
the male customer service Representative i spoke to then said I wasn't insured as my renewal wasn't done automatically, when I told him what had happened he basically couldn't have gave a damn and ive never ever been made to feel by any company in my life like this company has made me feel and now had me over for my money then dont want to know.
I explained I'd not had any letter, phonecall or anything to inform me i had to renew my insurance, the customer service Representative replied with we don't do that anyway it's up to you to phone and do that yourself!!!!! Then basically said they wouldnt be insuring me anymore now due to my IN10 conviction!!!!! ARE you lot for real!!!!! So I've then looked up the FAQS regarding renewal of car insurance which asda PROMISE THEY WRITE TO YOU IN GOOD TIME TO REMIND YOU OF YOUR RENEWAL ASWELL AS TELEPHONE YOU TO ALSO REMIND YOU!!!! SO THANKS TO THESE DISGUSTING PEOPLE I NOW FACE ANOTHER NON INSURANCE AND A INDEFINITE BAN. IM THE ONLY DRIVER IN MY FAMILY AND RELIED UPON BY MY 87 GRANDMOTHER WHO HAS NO OTHER FAMILY AND LIVES 20 MILES AWAY TO TAKE HER SHOPPING EACH WEEK ASWELL AS RELIED TO TAKE MY MOTHER TO WORK TO KEEP THE ROOF OVER HER HEAD BY PAYING A MORTGAGE AFTER MY DAD DIED.
