I need to terminate my contract for landline internet. I'm moving out of Germany. My contract seems to be for 2 years, but I have ordered a contract for only 1 year. I do not speak German so I think that is why I did not notice that there was a mistake in the offer. Now I already have to leave the rental apartment, and I am abroad. I have tried to contact Vodafone by phone, but that is apparently impossible.
