Bunch of ******

This is actually a no star review, my sister and i bought Blue tickets in January for the March show which was postponed till October. October rolled up and the Blue concert was cancelled and my sister made contact with Itickets just to hear they not handling it because Toptickets took over, why were we not informed that they switched?? So we got a number for Toptickets which was non existent ofcourse!! Needless to say i’m still waiting on our refund, because why is there no one responding back to us?? Are we suppose to just forget about our money??
