I generally find JB Hi-Fi to be OK (before someone accuses me of having an axe to grind).
While waiting on the 135244 phone line (which is the only way to contact JB Hi-Fi online apart from chat), and getting a slow count down from 'you are number 15 in the queue'; when it reached number 3 (after 1 hour 7 minutes of hold music) a new message came up stating they were taking a large number of calls and to call back later. The call then disconnected.
It appears when that department knock off for the day at 6pm, they just turf the waiting customers. I am guessing there were at least another 15 waiting behind me.
It is kind of funny, as it really is the perfect way to upset a customer. Waste their time and then make that waste of time completely worthless by cutting them off.
A lot of effort for me to get an $8.95 overcharge fixed up.
Maybe that is why they do it.
(And the wait time for chat is just as slow, but does not cut off at 6pm).
This is how dictatorships start.
