want to renew comodo

i am trying to renew comodo as it runs out soon but when i go in to site to renew it asks for email address and password when i put these in it says incorrect yet i can log in to my account with login name and password.
i contacted chat and they can only offer me 12 months with auto renewal,
is there no way i can just purchase 12 months subscription or do i have to find another security provider
i have been with you for at least 3 years

interesting seems i have auto renewal. i did not un check the box 3 years ago so it renews every year.
so i need to get that stopped.
same old story you get punished if you stay loyal to a company. :-TD
