Huh?!
I just phoned the insurance to add Kevin and Michelle on the coverage, which supposedly was a simple matter of adding their names. However, after a long wait, the operator got back to me and said that having three unrelated people living at my home did not fit with the policy I had and that they would be cancelling it from the 24th of September!
She then kindly gave me the number of Financial Ombudsman Services where I might be referred to "something more suitable".
WHAT!!!! Fuck this - Kevin talked me into doubling my cover which increased the monthly premium from $27.88 to $59.64, and then didn't pay the difference because "his and Michelle's names were on it" (that is, they wouldn't be covered). No there's no coverage!
