The server came in with a defective… The server came in with a defective hard drive. I prepaid for a new one. It has been since July of 2018, it is currently November 2018 and I’m still waiting for the refund of the returned defective part. I keep being told that they are reaching out to accounting ASAP.

Re-seller misrepresented their product… Re-seller misrepresented their product on Amazon. I ordered a refurbished computer system advertised as 2018 Dell tower. Found out it was actually manufactured in 2014. When received it was missing the keyboard and mouse. I notified seller of issue and they promptly offered a wireless keyboard and mouse upgrade and $100 if I would remove my unfavorable feedback. I agreed with the offer and complied by taking down my review. Received a regular keyboard and mouse and never got the $100 credit. They never responded to another email. Contacted Amazon. The said seller violated the rules by asking to take down feedback. Very untrustworthy. Do not buy product from Aventis Systems.

Aventis systems offers a failed configurations in servers Aventis systems have many solutions in servers incompatibles in memory type and CPU models. I buy a promotions offered for aventis. Buy one and get one (bogo). In this promotions they offered the processor intel xeon L5520 with memory 1333MHz. The servers has been received but memory is 8500R (1066MHz) and never I was never notified of the change. When I complain that I did not get what I asked for on my bill they indicate that they are incompatible (since they promoted and armed the solution). they asked me to solve the problem I must buy another CPU. They have not sent me the memory I bought yet.

Worst company In North America Worst company In North America! I ordered a two pack of monitors on new egg.com in mid February. They only sent one monitor. Then they accused me of lying to them. I sent them a total of 12 pictures showing only one monitor was delivered. Newegg finally gave me a refund that was early March it’s now almost April and still no refund. This is a company of thieves. Save your money go elsewhere!

Buyer Beware! I ordered a $640 Dell monitor from Aventis Systems through Walmart's marketplace, but received a lower-quality $400 HP monitor. It was a gift for my wife, so we didn't discover the problem until she started having problems with the monitor a few months later. We reported the issue as soon as we discovered it, but Aventis Systems couldn't care less since we were outside the return window. Apparently after 30 days, it doesn't matter that they essentially stole the $250 difference between the two monitors and left my wife with a lower quality monitor that can't even be repaired under warranty since we don't have a receipt. If you look at their reviews on various platforms, it appears they do this regularly. Do not buy from this company (and make sure they are not the third party seller on another marketplace) - you will regret it! There are plenty of other reputable sellers to choose from.
