1 MISSED PREMIUM, POLICY CANCELLED(REALY??????)

I used to rate Outsurance highly but not anymore. My father skipped one premium of his car insurance and they cancelled his policy. My father is a pensioner, I used to pay for his premiums before I lost my job last November, I then spoke to my father about taking over the payment, I then stopped the debit order from my side.

I don't know why my father did not set up a debit order from his side, he did not pay(REMEMBER HE IS A PENSIONER). But WHY IS OUTSURANCE CANCELLING THE POLICY WITHOUT CALLING MY FATHER? IS IT BECAUSE MY FATHER NEVER CLAIMED AND IS CLOSER TO GETTING HIS OUTBONUS? WHAT DOES YOUR POLICY SAY ABOUT 1 MISSED PREMIUM OUTSURANCE?

REINSTATE MY FATHER'S POLICY IMMEDIATELY OR ELSE I'M TAKING YOU TO OMBUDSMAN AND YOU WILL RETURN ALL PREMIUMS WE PAID SO FAR. REISTANTE POLICY NOW, WE WILL MAKE AN ARRANGEMENT TO PAY EVERYTHING.
