Groupama Insurance Skyrocketed Its Prices For Elderly

My parents are elderly, one is 75 and the other is 77 years old. They have been paying premiums for Groupama health insurance for years. Last year, the premium was set at 29,197 TL, but this year it has skyrocketed to 199,256 TL. It is an outrageous act of consciencelessness, lack of empathy, and ethical deficiency to apply a staggering 600% increase in premiums for an insurance policy that we have been loyal to since 1997 and which cannot be canceled for a lifetime according to the contract. This blatant exploitation demands immediate action and investigation. I kindly request that appropriate measures be taken regarding this situation.
