Why no one answer the phone fir customer service. The phone ring pick up and hang up. Why is that?

Happen to me today

Unfortunately, Best Buy has switched to a Phone Hub model. So when you call a store, your call gets routed to a Hub store, where they then will route your call to the correct store if they can't help you first. The only way to avoid this is by knowing an extension when you call the store. Customer service at every store is either extension 2100 or 2020.

That's odd. Maybe they are having phone issues. Try tge toll free number, maybe the customer service line can contact the store manager for you.
