wrong address in my new contract!!!!!!!!

[hc830000]

I have just ordered a new contract, but you have typed the wrong address!!!

I don't know how to correct, but only select "Umzug Service". 

Ridiculous! The whole new contract! 

How can I correct my current address?

Which federal state do you live in and which tariff did you order?
