donation problems

Good I am a small donor who began to enjoy it, which made me the idea of ​​donating the whole heroic set, rings and beads of all my pj little by little since I have three accounts one with four pj and the other two with two each. This account donates 100 dollars my second account donates 50 dollars and when I was about to donate 100 dollars to my last account I find a problem that I did not have in my country before, I can not donate and paymentwall does not give me options or with mint , neither with transfer nor in cash. After many communications via gmail with them and do everything they asked me how to try with other browsers, clear the cache of the website, try with mint and other things I definitely can not donate it can be said that my country of origin is Costa Rica. I also reiterate that it never happened to me before and because I would like to be able to continue donating, final paymentwallal gave me as an answer that they were going to happen with the developer and that they would be contacting me when there was a solution but we are already months away and I still have the same problem . What I want to know is that I should and can do or if I give myself to the idea that I can no longer donate ... I need you to advise me ... thanks.
