I was pleasantly surprised when I received a call on Monday from San Jose SC manager, assuring me that they would make sure to arrange me an Air loaner.
Since then, the situation has only improved. I received my Air loaner on Tuesday as promised. On Wednesday morning, I received another call informing me that my Gravity requires a battery replacement, and they are currently working on it.
They also asked if I would like to switch to a Gravity loaner, and I happily agreed. They dropped it off at my house today!
I'll admit my impression of this particular SC has completely changed since just a few days ago.
