I bought tickets months in advance for Diana Ross concert June 2, 2018. Days before the concert I called about my tickets. The seller could not be reached. They offer little help and no refund. I see other reviewer who experienced the same. Do not use this scam operation. The reseller listed a phone number that did not accept incoming calls. There was no way that BoxOffice Tickets Сom could have ever contacted this reseller to verify they actually had tickets to sell. I had to contact my bank to dispute the charge. Thank goodness my bank went to bat for me and I received a credit back while they investigate. This company guarranteed ticket by a certain date. Beware!! Proceed with caution when dealing with this operation!
