Cant change start date

I called Auto and Genera requesting that, they pros-pone the activation date of my home insurance, as the house has not transferred into my name, after waiting for 25 minutes I was told its not possible, however in June when i took up the policy they were able to to move it into a future date, now I must pay premiums for a possession that is not in my name, this makes no sense to me please assist in amending the start date and stop debiting me until then.
