Yeah, the post is a bit ambiguous but seems like you may be right. If OP had GV, then ported to Fi, and then cancelled Fi service without porting his number that would fit with the complaint in the post. I'm actually somewhat less sympathetic in that case. When you cancel phone service without porting, you lose your number. That's how the phone system has operated for decades. Why someone would assume that cancelling phone service would somehow automatically sign you up for a different service is beyond me. But I suppose the confusion is related to people thinking GV and Fi are "the same" or "built on each other" (e.g. see comment from a Googler elsewhere in this thread) since both services give you a phone number and both services are run by Google. In fact they are essentially entirely separate services from the perspective of the phone network. GV is based on Bandwidth.com's landline VoIP numbers, while Fi numbers are actually registered by T-Mobile.
