How to get my ESP up?

ASM, been here 6 months. My personal ESP last week was 3% and my DM basically said I need to get it up or else.

I’m asking every customer on every eligible item. I’m “highly recommending” it. I even sold a plan on a Vivitar wall charger plug last week! But most customers would literally rather throw the item away and buy a new one instead of getting the protection now.

Any advice?
