Bad service

This company fixed my fridge 6/11/2019. I broke after a month in half. He gave me 3 month guarantee. I called him after a week to tell him the top part doesnt freez. He ignored me After a month and half i called him and tell him it stop frezzing he must come and fix. He keep on ignore me and say he will come out. I lost a whole month of food and no freezer. I told him i will sue him. But it will cost more than my damages. Now i must pay someone else to repair his ****ty job.

Can you maby help
