poor customer service, cheap product

I bought a solar light security light from this company. Icame with fully charged battery and strong light, so I assumed that it worked fine and did not return it. When the battery was off it stopped working and never worked from solar light as it was promised. I contacted the company many times but did not get any refund, replaced item, guarantee, information about the manufacturer, nothing. They did not reply to most of my e-mails. Solar light came with a stange battery which I cannot find anywhere as it is bigger then usual AA battery and unbranded. Completely waste of money, extremely disappointing
