I'm not a German speaker, I've signed for free-email account at GMX, send an email to support to change to language to English- no answer.
Then after a while I've got a bill of 40euros for things I never asked or signed for!
Contacted the support again - no reply until 1 month or more.
I ignored them then got mail from Inkasso to pay more. Now I'm gonna see a lawyer to solve all of this! Scammers..
