Then, sorry, your situation stays a mystery. The combination of what you describe that you can do and not do, is unusual; doesn't really sound like "banned".
So, did you get a reply from CS meanwhile; if so, what was their explanation or advice? If the latter, did it help? if not, why not / what happened instead?
Or is it solved meanwhile anyway?
If you didn't get an answer yet: had you replied to the first automated answer, BUT not to the 2nd?
