Hi @Forgotenking, welcome to the Community.
Cashback claims are often frustrated by the method of payment you use. Sony always insist that the bank account used to purchase cashback-eligible products is located in the country that the offer is made in. This is because the cashback payment is made direct to a terrestrial bank account.
Is there a reason you used a PlayStation account to purchase the camera? This will add another level of difficulty to the process, as you have effectively involved two accounts in the purchase, both of them located outside the country you bought the camera in.
Unfortunately this makes it unlikely that your cashback claim would be honoured, as far as I can see. I could ask around and see if there are any exceptions to this but I've never heard of one.
