India, Jan. 16 -- On Wednesday, just days ahead of American singer John Mayer India debut concert in Mumbai's Mahalaxmi Racecourse on January 22, the organisers announced that the show has been postponed to February due to 'unforeseen circumstances'. The news of the concert's postponement has left fans heartbroken. Soon after the announcement, fans eagerly anticipating the concert expressed their anger and demanded full refunds. Some questioned how they would reschedule their flights, as they had travelled solely for Mayer. A user commented, "Explain this to the airlines where we booked flights." Another asked, "Who's going to refund my flights and tickets both? Where's the refund option?" Another fan pointed out that the show was only a week away, and they had booked non-refundable accommodation and flight tickets. They argued that the financial losses from cancellations were unacceptable. Tickets had been booked from across India for Mumbai, with people arranging their jobs and work schedules in advance. "Omggg this is so disappointing! We have booked tickets and hotels for this. Some of us are coming from so far away! Please refund the concert and flight tickets. We are working class people, and we work very hard all year to save and buy concert and flight tickets and book hotels. This is not done!" said another user. HTC...
