Problem donation

Hello. I tried to donate via SMS(mobile Payment) from Bulgaria to donate but when I enter a phone number it said to check the number again but it is correct. I tried to donate from multiple numbers and even used proxy but still can't donate that way. Next, I tried to bind my phone number to my account which said it would be 4.86 BGL and I entered the code in the SMS two times and it still says that is incorrect. I don't know why this happened but I want to donate and I can't find out how. can someone please help and at least bind my phone number because I sent 2 SMS and it says the code is incorrect. the number I donated from is +3598761512** (I will give you the last two numbers if they are necessary via a private message). Now when I try to donate all I see is a black screen and it won't load. Can you give me a bank account or PayPal maybe because I can't donate this way and I can't use the Paymentwall. And please check that I bind my phone number two times and still it says that it didn't work. Thank you in advance!
