I live in Bentonville and I can tell you it's a mess. They switch IT contractors every few years because each one agrees to more than it can handle to get the contract.

Just recently, like 2012-2013, NCR had it. CompuCom made a killer deal which they couldn't actually afford and cut a lot of corners and provided shitty service because they didn't hire enough competent staff.

CompuCom lost the contract to NCR again, so everyone in CompuCom got laid off. Now since Toshiba bought out IBM's "Retail Store Point-of-Sale Solutions Business", they also hired on their own support team, a lot of them were previous CompuCom employees. There's layers and layers and layers of tech support and bureaucracy, it's amazing anything ever gets fixed.

Their inhouse service, "Information Service Desk", or "ISD" is full of people here on H1B visas, shoulder to shoulder in a huge building called the "David Glass Technology Center". There are no cubicles, just long rows of tiny tiny desks.

It's a damn terrifying sight.
