Bought a Parabolic Reflector

I bought a parabolic reflector from this company, but they delivered a complete piece of shiet. When the delivery team brought the package, I wasn’t keen to check it at first because I was a little bit positive. However, when I opened the package, the reflective inner parts had completely peeled off, and even worse, it had some holes meaning some light was going out. I emailed the customer support team, and they didn’t respond to my email until I sent the third one. They promised a refund, but I haven’t received anything from them two months later. I wouldn’t recommend these Cons!!
