Credo Mobile "Progressively" Predatory San Francisco, California

With the intention of spending our cell phone dollars with a company that professed to help causes that were "green" and " progressive" and "pro- women/ humanity" we chose Credo Mobile...feeling like we had " joined" a cause.
But, quickly, there were problems..in fact, from the first bill things were wrong & correcting them was always difficult & time consuming. And I had to go over our bills every month to see what we had been overcharged for. And, thus, I never switched to a paperless bill even though I always do & their paper bills were MASSIVE & tedious & very confusing. Plus they were forever "rounding up" our bill & adding other "donations" that we had not agreed to onto our bill!
When our contract was up I bought everyone new phones with another carrier & had a HUGE hassle trying to get Credo to switch our numbers to the new phones..took me about a week (& many calls = HOURS on the phone) to get them all transfered.
Nearly a month after switching I got what was supposed to be our final bill and, of course, it was wrong. They had a full month of charges on the bill rather than a couple of days. I called & their rep said that I should just wait as the bill must have been automatically generated & a correct final bill would be sent. So, I waited. Weeks later another bill arrived and it was even LARGER! Now they were trying to charge early termination fees! Yep, I called again...rep checked and confirmed that someone had indeed "made a mistake" and this time I demanded to know what the correct bill amount was (even though he said a new bill would be mailed to me) . I IMMEDIATELY sent them the final payment and have not received anything else from them..yet.
Meanwhile, I listed & sold 1 of our used phones on ebay.
The buyer contacted me afterwards & says that Credo won't activate it because she "bought" a 3rd party phone!
For a "progressive" company these guys really need to get someone in to correctly set up their billing, learn something about customer relations, stop trying to shake people down & ..geez, really? Stop refusing to activate a Credo based phone for another customer? What right do they think they have to do this? I am amazed that they have any customers left!
