Full refund please

Full refund please

Hello, good evening.

I received an email regarding the postponement of the show on May 8 in Detroit. I tried to click the reschedule link given but it just takes me to the regular home page, so i did try to put the code (which was supposed to be the name in the receipt) in the promo code section after i tried to buy tickets for the other date of the show, but it continued to say invalid code. 

 I sent an email three times already (5/6, 5/10, 5/25) to the detroit fork n’ film to help with rescheduling but no response.

So we are hoping for a Full Refund instead. 

My order no. Was 2ZZT-T5DR-X28

Hoping you could help us with this problem.
Thank you very much and have a great day!
