Onedaydiscount — solar light not working

I have ordered two packs, with each 4, solar lights. The shipment took very long, i think it was over 2 months. After i received the lights, only 2 out of 8 is working. I hope they can solve the problem for me. However, when i tried to check the facebook again, where i firstly found the products, the account has gone. I think the company is not doing proper business or it is too shameful to receive too many bad comments. Can anyone give me a reply?
