Virus infection by mail order? I ordered mask filters from Banggood. They arrived very fast by mail shipped from The Netherlands. On arrival I immediately noticed that something was wrong. The boxes labeled with the 3M logo had a seal of authenticity and every single seal was broken. Wearing gloves and mask I carefully opened one box to find out that the filters had already been used. They were dirty and had traces of use. One 3M box contained different types of filters. Someone along the chain of delivery is having access to pre-used 3M medical supplies - and is selling them. I dare not think about where the filters have been used. I did get in contact with Banggood customers services. I thought that they would be interested in finding out about the associate seller being involved in this dangerous business. I did document my findings with photos and descriptions and provided every bit of information I was asked to provide. I was certain that Banggood customer services would do something about the matter. I was, and am, open to the fact that my assumption is wrong and that there is a plausible explanation to my findings. Customer services did indeed tell me that they would investigate the case and contact me with the result of their investigation. Unfortunately, nothing, as in absolutely nothing has happened. They do not take this seriously and I am still able to press re-order the exact article that I ordered. I have spent quite some time trying to get information about the case, but I am being totally ignored. Since Banggood takes no interest in the matter I believe that a warning should be made to the public not to buy protective gear from Banggood. No one should catch a virus by mail order!
