It seems like this rating comes from consumer ratings though, and it's not very likely that people are going to report a wonderful job to the BBB. There are 37 complaints over the last 3 years, considering the millions upon millions of customers, that's actually not a bad record.
And like I said, when's the last time you reported something to the BBB when you had great service? Exactly.
And interestingly, it looks like 26 of those complains were resolved, 1 was resolved according to the BBB but not the customer, 5 had no response, and only 5 were handled unsatisfactorily according to the BBB.
So of 37 complaints over 3 years, the vast majority were resolved to everyone's satisfaction, and 10 were either ignored or unfixed.
That uhh... really doesn't sound so bad to me. At all.
