I received a follow up Customer Service call from a senior CSR today due to some CS issues I had with my order and information received from their CSR's and also the ones at my local store. I was not expecting the follow up nor did I request it, but it was nice nonetheless.
The person I spoke with today told me that their numbers in terms of pre-orders was far higher than either AT&T or Nokia was expecting, which is what led to their lack of ability to fill all of their pre-orders in a timely fashion. She was very open and up front about the fact that this should not have impacted their ability to provide good and accurate information, but it does at least explain how the main problem, not shipping phones on time, occurred.
