Terrible customer service

I ordered from Vitatech Health on the weekend of Black Friday. My order was delivered on the 4th of December. To my surprise a small box with only 4 bottles. The rest of my order seems to be missing in action. I reach out to them, and they never rep**** back. I finally decided to try for a solution and send a message on Facebook (x 3). That person promised that the rest of my order would be delivered last week. Needless to say, I am still waiting!!
