I've had to deal with the call-in support twice in last 6 months and each time I was asked for my actual password (no one asked me for any 'telephone password' but I don't have one and even if I would, I wouldn't tell it to anyone either). Given I wasn't inclined to do so, after trying to explain how wrong this practice is, trying to escalate it, in the end I've meet the similar wall of 'we are sorry you feel this way, can we help you with something else?'.
