First time order with a new supplier for stickers. I was very clear about needing a split back sticker. Simply means it's easier to peel because the backing is split down the center so that you just slightly bend the sticker and it's easy to remove backing paper and then stick to surface. That's important for my customers because they are often wearing work gloves and it's super easy to open the sticker with a split back. Otherwise, they must remove gloves and use fingernail to try to remove backing paper. Stickers I received did not have the split back. Alibaba only refunded a portion of my money, about 1/3. VERY disappointing but even more frustrating was how they treated me. I tried for a month to get them to see my side but it was like chatting with a bot every time. No willingness to be helpful. Very unprofessional and bad customer service. Next time I will test out product with smaller order and then either use a different third party escrow service who actually cares about that role. A true fiduciary will hold on to the funds until I am 100% satisfied and if the seller deviates from the agreement then I get ALL of my money back. Obviously on larger order I would also enlist the help of an inspection service but definitely someone outside of Alibaba. Do not rely on Alibaba Trade Assurance to provide you with actual relief in the event of you getting scammed by the supplier. Another alternative website that I am having better luck on in made-in-china.com because they provide actual escrow services. I spent nearly $25,000 through them so far and no problems, they held on to my money until I confirmed the purchased goods were in good order. I am starting to take more of my business to MIC for that very reason. AND, even better, their escrow service didn't cost me one more dime! Whereas Alibaba added insult to injury by providing terrible customer service, kept 70% of my money and charged me a hefty fee for the privilege of being screwed. And didn't even offer me breakfast in the morning. My advice, beware dealing through Alibaba.
