Purchased a 3d printer with upgraded mainboard and glassbed. Glassbed received, mainboard was claimed by Banggood CS that is already installed in the printer. "Where is my old mainboad?" this is my question? Goods received on end May 2020 without maindboard, correspond with Banggood CS, and they request (first) photo, then (2nd) video. After few exchange of mails, Banggood CS claimed waiting for supplier to respond. Complaint written in their website, and email, replied from Banggood "will get back in 5 workings", after 8 days, i wrote again, and promised from Banggood that will reply within 3 workings. After many 5 or 3 working days, the case seems to die of nature cause. First and last experience to use Banggood online shopping. Worst of the worst I ever come across. CS can promise after promise for respond. Just imagine your purchase didn't deliver to you??? you will be at their mercy. I take these opportunity to highlight to those did not try Banggood before, do keep a look out for other choice which will not have to the same encounter as me. There are many choices of online shopping, DO NOT USE Banggood, at your own risk. I used few online shopping which did not have such bad experience. Thanks for all your listening ears (Attached 2 eg. of email)
