Unfortunately, I had to give a one for tech support; it deserved a ZERO.I purchased a computer on January 4, and it was apparently riddled with major problems and maybe a virus. I was told to send it back, and I did.  It was an Optiplex 9010. In return, I received an Optiplex 7010. I didn't understand the difference even after researching it.I had never worked with Windows 10 as  I had always used Windows 7 Pro, but the support for Windows 7 was expiring.But the biggest problem is the customer doesn't get any support from this "company." Phone calls are ignored and never returned. I was told to call before 8 a.m. or after 4 p.m.  With the pandemic, I am sure one of the techs could have spared a few minutes to answer three questions I needed answered.I finally, I got through today and was told that the time for coverage and support has expired.  I paid over two hundred dollars more than the order I had originally placed.  I am not an IT specialist, just someone who expected to get some support for what I had paid for by answering my questions about that I have. I don't know the value is of what I received; apparently less than the first computer that was shipped as that is what the tech manager told me.. It would have taken three minutes or less to answer my questions. Not nice people.  Would NOT buy from this place again!Pretty arrogant and rude,
