SERVER ERROR - When purchasing Theme

I am trying to purchase the Taiga theme after spending almost a month customising it. Every time I click buy it gives me a server error. I tried a new card, clearing my cache, checking my bank, waiting a couple of days… I check my billing and apparently it has been refunded to me, but no funds come out in the first place. Nothing is working. Just keep getting a very vague server error.

I can’t make my store live without it so any help would be much appreciated

Hey,

Could you please share the Screenshot of the error that you are facing.

Thanks
