Impossible to call the Warringah Mall store on a Thurs mid-afternoon to get info if an item is in stock or can be ordered. I was transferred about 5 times - every 45 seconds or so - and had to keep re-explaining to new people, despite knowing the exact brand, make and item I needed. A collosal waste of time, terrible phone system (instead of being on hold, it would beep so others would pick up anywhere in the store) and terrible pass-the-buck cust srvc personnel. Calling is a complete waste of time and an unnecessary aggravation. JB is mistakenly listed as providing automobile stereo parts and equipment but is unable to provide the service necessary to do so. Terrible.
