I left my last role mid-March. I filled out all the forms for IT to collect my equipment. My final day came and went and no word from them. About a week later I emailed HR to say that I still had the laptop and they said they'd send a box out to me with details on how to return it. It'll be 3 weeks on Monday since that email and still nothing from them. At which point do I say screw it, it's not my responsibility to arrange the collection of your equipment? Note: They're a big American tech company btw, if it were a smaller business I'd be doing more to get the equipment back to them.
