Unhelpful and faulty booking system

I am so frustrated with Webtickets system and customer service. I an trying to book an event in 2 months time at a pensioner rate but the system will not acknowledge I will be a pensioner then as I turn 60 in a month’s time. I patiently explained to Michaela at webtickets that I will be a pensioner at the time of the event but they refuse to accept their system is erroneous and will not override the booking. They referred me to Artscape who were even more rude and unhelpful (I spoke to Portia and Keiran). Artscape referred me back to Webtickets.
