Increased premiums without informing

I opened a hospital insurance for my husband last year with clientel and I wasn't informed that my premiums would increase every year, just this morning when I try to call their help line to cancel this insurance they wait for me to explain then when I'm suppose to give them my id or policy number they hand up on me, I've been trying this for awhile now with no luck. What must really happen when I want to cancel a policy I do not want any longer and they keep hanging up the phone. I want to cancel this policy with immediate effect cause they even playing game's with my head by answering then hanging up on me. I've got recordings as well to prove how clientel treat their customers..
