Edit: So we're talking electoral systems, referenda have a big caveat. Usually you vote a goal, but you don't vote how it's going to be implemented. The brexit was sold as a measure against Brussels' regulation and taxes...

It was just as much party politics as the Brexit vote, not a genuine attempt at direct democracy.
Proportional representation and ranked choice voting are orthogonal concepts. A referendum for ranked choice voting doesn't necessarily implement proportional representation.
1. regulations around referendums (compared to general elections) are very poor and the "no to AV" campaign exploited this by running an extremely dishonest campaign [1]
2. turnout was < 50% of the electorate so one can somewhat facetiously imply from the result that the majority of the electorate don't care what the system is.

It's important to remember that the change on offer was itself deeply flawed. It was trying to apply a reasonable system for electing one person to elect a whole Parliament. However AV is not a form of proportional representation and would probably have resulted in an even less proportionate cohort of MPs at the following general election had the referendum result been the other way.
Some people were arguing at the time that it was a useful first step to establish popular support for the principle that FPTP had to go but others were arguing that AV was a poisoned chalice and voting for it implied that it was an acceptable alternative and would end the debate for a generation without really fixing the problem.
In any case, a referendum on whether to keep a fundamentally undemocratic electoral system is in itself undemocratic - there is no legitimate case for keeping an electoral system that effectively disenfranchises a substantial proportion of the electorate.
