Can your insurance ask you to pay for premiums that you have put a claim in to?

I have claimed on my ppi, that also covers my house contents. As I am no longer working, and to enable to meet my mortgage payments for twelve months. my question is: can they ask me to carry on paying these premiums even though I have submitted a claim and are unemployed. I was to understand that if you put a claim in to your insurance, that all the while the insurance was paying out on this premium that you did not pay a penny till your claim started again? Only my insurance have said for my policy to proceed, i would have to make sure that all payments are met, which they are, even through the claim. How can i be expected to carry on paying the policy when i am unemployed. also, they have put my house contents amount up from £35.00 to £47.00 since i put the claim in, and still paid every month since putting in. are they right to still charge you for the premiums, even though your unemployed? I have never heard of this. I am curious to be told the ans and would appreciate asap. thankyou very much. paula
