I ordered 8 tickets in total for the Miami open from 4 different vendors/people through Stub Hub. I received 6 of them and the other 2 never came through. I spent hours going back and forth on the phone and via emails with many reps saying just wait, you will get them. I ended up purchasing new tickets and disputed the charges, which may CC did not reimburse me for due to Stub Hub's policies of saying they will replace them with comparable tickets (this also never happened). I will never use Stub Hub or Capital One again, particularily when there are so many solid reputable companies out there.
