Hollard doing what they want

My father passed away end April, claim at Hollard was paid out fast, my mom selected the continuation option. Sinve then we have been strugling with this issue. We found out that the policy was cancelled, now my mom's premium is more than what is was when they were 2 on the policy??? Apparently her age is a 'problem' now. After several calls from Hollard stating the new premium, which we did not accept, the higher premium was deducted from my mothers bank account last night! We are extremely disappointed in this company, after the pay out was done very fast, even though there were a lot of public holidays involved.
