VFS Global Croatia Visa Registration Email Verification Not Working

I am trying to register for a Croatia visa appointment through the VFS Global online appointment system in the Philippines, but I am unable to complete the registration because the email verification and account creation are not working properly. I am using a Gmail address to register and I am sure that the email and password I enter are correct, but the system keeps saying they are incorrect or does not allow me to proceed. I have tried many times, on different browsers, and I have also checked my spam and junk folders, but I still do not receive any activation or verification email and I cannot create my account. I tried to contact VFS Global about this issue, but I have not received any response so far. Because of this technical problem, I cannot book a visa appointment, and I urgently need to secure an appointment as soon as possible. I kindly request that you urgently activate my registration email account or manually create and activate my VFS account for me, or otherwise fix this registration problem so that I can log in and book my Croatia visa appointment without further delay.
