Tmart Deceptive and Incompetent Hong Kong, China Internet

I purchased a Phantom 3 drone for Christmas in the states and needed to accessorize my new hobby. I found Tmart to be very intriguing and the inventory, prices, free shipping and no sales tax were very tempting. I ordered spare parts, cables, propeller guards, and hard back pack carrying case. I didn't expect fast shipping since it was coming from China, so I had my patient face on. The case was "lost" in the mail. Tmart customer service acted like they actually cared, but wanted proof of the loss or theft. USPS and FEDEX showed the tracking, but nothing was received by me. The prop guards and lens cover were the second shippment. The guards came in a box with no contents list. I'd assumed that they would come together since they were under one shipping order, but just the guards were in the package. Tmart said they needed proof of the loss. How do I prove that it wasn't sent to me? The proof is that I didn't get the $1.90 item in the package. They didn't even send me a packing slip. Third order was a ipad cable to connect to the controller. Three weeks after the order and it still doesn't show as shipped. They tell me that I need to send them proof that I didn't receive it. WHAT!! Are you kidding me!! It never even shows as being shipped and they want proof that I didn't get it? They are idiots, and the only customer care you get from them is for them to tell you to send them proof that you didn't get the item, or that it was lost. They ask what is impossible, then refuse to take your word. One lost item was over $60., but the others were a few dollars. 1 out of 4 items were received, and they would send them again, or check into their own shipping inadequacies. Don't make the mistake that I did and buy from Tmart. They are a ripoff and know they can get away with it because they are in China. They suck, and don't care that they do.
