Hello. I left Berlin three months ago and moved back to the United States. I just realized that I've forgotten to cancel my telekom Speedbox. My two year contract is not up, but we had to move back to the states quickly. I am now paying for the modem and have not used it since April. I saw that I need to deregister from Germany, but I've found that my building manager de registered us when they filled our apartment and they are not being very forthright with information, so I'm not able to get any paper work for deregistering . Is there anything else I can provide to close out this account? Thanks a lot in advance!
