Customer Service call computer hung up on me multiple times and I was never able to talk to anyone ever. They claimed after holding for them for 10-15 minutes each time that they were having a technical difficulty and I should try the call later. Each time I tried, same story. This was well within their normal business hours. This kind of customer service is totally unacceptable.
