Scdkey.com is not legitimate!
On 12/17/2017, I purchased 7 microsoft 2016 professional plus cd key global from them. they were supposed to be valid each for one year. one only worked for 6-months, (786nk-ccdx4-k8vjk-q8pf9-hcdr8). the others were either not microsoft products or were never activated, (m9nhb-w6qk3-rq98q-96dm4-r3j8w); (w77hn-txpb7-xym9v-7d927y-kd7f8); (4g6h3-bnyqm-w8wdc-923x9-hcdr8); vdccr-nbtdr-fqvfc-4g983-h2y2j); (jn88w-2g97r-h3q4g-27hrx-qv6jw); and (nkrft-frvkm-2ggm9-gjyrj-dgm2j).
Microsoft tells me scdkey.com must activate them before I can use them. god knows how many people have received the same key codes. I paid these crooks $145.04. by the way, they work under two separate names; (amzgame co., limited; and beizhou interactive entertainment co., ltd.)
Be extremely careful, the company operates outside united states and its website, (scdkey.com) hides behind godaddy in order to conceal its location and the true names of people who own it.
Lies...
