Shenzhen GTKPower Batteries Company review: Defective product

Ordered 150Ah LifePo4 battery from Shenzhen GTKPower Batteries Company in sept. 2019. Received battery defect, conclusion temp. censor not working, battery not take charge/decharge. Make proposal with the caller that I fix this problem, and he agrees, all huge procedure in chat with this company.
Now in March 2021 still waiting for compensation as promised, seller not response anymore to my reminder. This is not a trusted company, buyers be aware. This behavior will also harm AliExpress as trusted buyers platform.
