Up until recently, the US/Canada number on the support page was: 1-800-860-6990.
Today, I noticed that there's a new number: 1-800-961-6851
So, I called it. Whoa - the support options have totally changed, along with the 'sound & feel':
Old number behavior:
-You're greeted by a female recording with a California accent
-You have choices for Billing, Technical Support, or "All other issues"
-If no one is available, the phone rings a few times, and you go to voicemail.
New number behavior:
-You're greeted by a recording of Jack Linden, with a *thick* british accent
-You have choices for "Joning or using SL", "Payments or Billing", or "All other inquires"
-Funky electronic hold music
-Intermittently, Jack Linden comes back on with a "Customer Service" spot about the Lindex. When you first hear it, you think he's actually answering the phone.... psyche! Its just a recording!
-You go thru two repeats of the spiel about the Lindex, then go to voicemail - much longer 'tieup' than before.
I don't know about anyone else, but I'd rather just cut to the chase when calling support. If no one is available, send me to voicemail as soon as you can - don't make me listen to two spiels about the Lindex.
And now I'm all self-conscious about *my* accent
If Jack's accent is thick & hard to understand to me.... I wonder how intelligible my Michigan accent is to a brit
