I second katy’s comments. Please ensure that you inform your Bank in writing that you do not wish to renew. Watch the Bank statement like a Hawk. This is specially where the Bank has direct debit instructions.
I had my Car insurance paid out in a similar manner when the policy was cancelled and taken to another Insurance provider as a result I ended up have the Car Insured twice which is illegal.
You guessed it the bank is not accepting any responsibilty. I have little or no confidence in insuring contents wheter is UK or Spain as I know thay will just not pay up.
