I had that issue when I left a (15+ year) job with a company that owned the phone number I'd been using for both work and personal. Justification being that this was waaaaay back when mobiles were just becoming ubiquitous; Nokia 3310 days. Not just the hassle of re-connecting the accounts, but even knowing which ones were inextricably linked to the phone number to which I no longer had access. (I think I could have requested the number personally, but I wanted to make a clean break, and having a new phone number meant I was much more difficult to contact for any legacy issues I no longer cared about - double-edged sword)
