I am extremely disappointed in BigStub. I purchased 2 Box seats for the Miami Tennis Open one month in advance. Less than 1 week prior to the day I bought tickets for, they emailed me saying the was a 'technical oversight' and my tickets were no longer available but they could provide me other tickets in a different section (not box seats). I have hotel and flts reservations for this event, so cancelling was not a good option for me. I called within 24 hours of this email arriving. Once on the phone with me they now say they dont have those tickets either but could give me seats even further away. This was just a pure and simple 'bait and switch'. Their website says '100% guarantee worry free' - that is a pack of lies. They eventually provided section in sec 209... a far cry from courtside box seats and a bit of a refund. Extremely disappointed. This was going to be a special weekend. When it seems 'too good to be true' know that you are right! Never using them again!
