Safeway griller

A few months ago I bought a safeway griller at clicks in Hartenbos. I used it twice and it worked perfectly. The past weekend I wanted to use it again and now I can't, because suddenly it keeps tripping the power. I understand that I cannot return it because I no longer have the slip. But I will deifinately be a lot more careful if I buy any appliances from clicks again. And I will certainly not buy any safeway products again
