Ironically I have just had a response from support and it's abysmal. This was the response:
"Please be advised that the renewal price for your V-Ray Solo subscription is £358.80 and you were charged with VAT this year, therefore the total amount is £430.56.
In accordance with EU VAT legislation, VAT will be applied only to orders in those countries where exemption documentation or a valid VAT ID has not been supplied at the time of payment.
Kindly share your VAT ID in order to validate it and refund you for the VAT amount. "
I've got two issues with this response
A). I don't even have VRay Solo, I have Corona Premium.
B). My issue isn't that I've been charged VAT. It's that I've been charged VAT twice.
Incompetent isn't the word. Corona Devs, I suggest you go and have a word with the uneducated support team as they're really pissing a lot of us off right now.
