Problem communicating with Mojang Support on Firefox

I am having a problem logging into my Minecraft / Mojang account that has already happened a few times (password reset is done), but last time I did not receive the password reset email, so I tried to contact the Mojang by email, I filled it in correctly, when I clicked to send the website prevented saying that I am probably a BOT and asks me to do a captcha test to prove that I am not a BOT, but there is no captcha test to be done, I am stucked in this problem for approximately 3 months.
