I feel your pain and can't imagine how it is NOW. I worked Pro Support back in 2016-2017 and it was the same cr-p. I was first shift so there was like 60 of us and we had 2 mins of "off call" time as well. It was ridiculous. I felt like a child.
Everything was "timed" for us. Gotta go take a dump? Better do a power dump because you only have a few minutes, otherwise you get "docked." 99.9% of my calls were from the US and native English speakers but, at some point I began getting sick of how we were being treated and simply didn't care anymore.
Then I found out a way to terminate the "ICE" program they used - which was how they recorded, monitored, and could listen in on our calls, at least in 2017.. - so I'd ki-l that application every morning after taking a few calls. Which made it seem as if it was an issue with the app. It worked for 2 hours then, stopped working!
Which was funny because a solid like 50 days went by without anyone noticing and then during a 1x1, they mentioned something about how they have no records of calls or whatever. I said "idk" and that was the end of it lol.
If the issue was something I didn't want, or know anything about... I'd swiftly transfer to network support and move on. I'd work with them for long enough (10 minutes maybe) then I'd transfer them to network L2's usually because they 100% will help someone.
I'd take note of the name so if I saw that name pop up again that day, I'd let someone else get it. The trick was to either not create a ticket until/unless you wanted/could help them out OR, create a ticket and then make up some bs in it as to why you transferred. I had a whole system worked out and don't remember what/how I did everything now..
If the customer was an A hole and/or a B to work with, I'd start pressing the mute button as fast as possible while talking - to make it sound like a connection issue - and then straight up hang up on them and/or transfer them to a totally random department. I had a few departments that I'd regular transfer people to lol.
Another trick I did if I wanted a break was to call my own cell number and let that "call" go on for 10 minutes or so. As far as I knew, even with the "ICE" program shut off, they could still monitor who was on a call and who wasn't. They just couldn't see anything more than that.
I did the same thing at another call center/MSP that I worked at for 3 or 4 years as well. Ironically, I quit that job to GO to Dell and get involved in the WORST call center I've ever experienced.
I quit in either late 2016 or January of 2017, then got a job as a network admin at another job. Then ironically enough, I ended up back at Dell in my dream job! 6 years later and still love my job - not the company, just my job lol.
