Lenovo ThinkSystem ST50 Tower Server Including Intel Xeon 3.4GHz CPU, 32GB DDR4 2666MHz RAM, 6TB HDD Storage, JBOD RAID (Renewed)

Buying lenovo st50 v.2 server was the worst decision ever . After I opened and discover what kind of shady practice lenovo does ( you cant use your own hard drives or ssd !!!!! ) I returned it and bought something else for my business , now thats not end . When I called 3 weeks ago lenovo confirmed that they have received it over a month a go and It should take few days but I have never received refund . Im calling my credit card company this week if I will not get my money back . WTF Lenovo !!!!Update . After many calls to lenovo and empty promises of refund within next few days I called my bank and filed claim . I have few lenovo products but after this will never buy anything from lenovo ever again .
