Once you put the USC put the correct mailing address, they should receive NOA1 and all subsequent NOA's relevant to his side of the affairs. If you haven't received anything yet it doesn't mean there is a problem per se. It means that it was either lost in mail or they only claim to have sent it since they lie to you quite often. Just let the USC call the customer support and explain they never received NOA1 hard copy. You should receive email notification however if you signed the optional form.
