Our previous ISP kept after us for a few years to return their modem/router. Only problem was we were a BYO account - we never had a need for their device, nor was it ever on our account or any invoices. A few years later, and every few months afterward (typically after I’ve had to contact them to solve the hell that was constant dropouts - reconnecting 2-4 times a minute) the missing BUDii would pop up again and they’d demand we return or pay for it.

Each time I got snarkier and snarkier, treading the line of being polite and sounding like I wanted to chew their face off. Then I got Betty (fake name) who asked for a moment while she read the correspondence on our account. She commiserated with the troubles we’d been having, clarified notes on our account and then solved what a dozen others couldn’t figure out, and we never heard about the BUDii ever again.
