I CANNOT change my Steam account E-Mail address.

A few days ago, I tried changing my E-Mail address on my steam account via the desktop client, when verifying the code for the new E-Mail I always got "Error 2". Tried it on browser, tried on my phone, Wi-Fi, mobile network, SAME EVERYWHERE.

Second thing I tried was the support form for changing your E-Mail, but there I KEEP getting the message "We had trouble verifying your captcha, please try to complete the captcha again.". I tried it on browser, desktop, cleared caches, cookies etc. NOTHING WORKS. There also isn't any visible captcha appearing at all.

I waited for a few days and tried it again today, still nothing. I don't know what to do.

Any help I would appreciate SO SO MUCH. Thank you in advance.
