I feel the same. M3D have the worst customer service I ever experienced in a 3d printing company. I ordered a 3d printer from them and they didn't email me about the ETA. When it arrived 2 weeks after I started using it and it seems working well, but after a while I had some problems with the nozzles and filaments and I started contacting their support, but to no avail. I've been sending emails but I just got ignored. Until I became frustrated and just give up for their crappy services. I am never buying from them again.
