It's really not a problem, the address only matters to get the documents to you.
Just have your TA call DCL to correct your reservation record and just cross out the incorrect information on your documents and write in the correct information.
Can you move? No, seriously just call your TA and advise them of the mistake. Depending on the TA you used and how trustworthy they are you can stop there. Or if you were a major worrywart like me, you would contact DCL directly and ask their advice. If they need to reissue docs, they will most likely fed X them to you.
