Hollard don't want to downgrade my premiums

very bad service from Hollard. I want to downgrade my premiums. been emailing them and no one attend it. I called and the call got dropped after 5minutes. they don't even call you back. I call again for another 10min, they say they cant even change it now, apparently system issues, I must call again in August. when joining everything is very smooth but when you want to do changes in the policy. It's too bad. I suspect even claiming is like this, i always heard people complaining now i understand.. I will join another policy and after my waiting period there i will be leaving this company.
