Long ago I had some contact with Wipro. We sold Wipro equipment and they'd sell it and their services to their customers.

Wipro would call up our tech support and declare "it's not working fix it, and you need to explain to our customer why it's not working". Basically they would outsource their own work to our support teams by reporting everything as a technical problem. In truth they just rack mounted equipment and connected cables and did nothing after that.

Wipro got real mad when on a few occasions in front of their clueless customers I said "this has never worked and has never been configured to work, can't fix it if it was never right...". After a while they stopped putting me on conference calls. Boy did they try to get me in trouble with my bosses a lot, never worked as I was good at documenting things.

Lots of their customers had backup systems that never backed up a thing, for years (if ever) ... but the customers also had nobody employed who would know better.

It was a shocking thing to witness. These companies were totally dependent on their outsourcing and they had no idea what was going on. A few of their customers were "critical infrastructure" type companies.
