Terrible customer service

Assupol is so frustrating, I've been trying to get hold of their client services department and it's been ringing until I couldn't wait any longer and hung up, when I tried calling again same thing happened for 4 times until I decided to opt for the sales department which they answered so quickly and as soon as I mentioned that I wanted to amend my policy the lady was irritated, didn't even advise me that she's gonna transfer me just straight up transfered me to the client services department which still rang without any answer. They don't care about existing clients, they care more about getting new clients, this is so disappointing I'm actually over these people
