I need to know how I can cancel my tickets ... with the temperature at 52 it is impossible to meet the objective ... please, what should I do to cancel the tickets

Tickets are valid until December 31, 2021. You can use them whenever you want.

It would be good if you call where you bought it and tell them about the weather you want to change it, or, in my case, when the tickets were bought the pandemic began, but I went almost a year later and they still worked. So, it is good that you call the supplier or vendor who provided it.
