No offense intended, but it seems your issues are related to mixing agencies used for the Classroom/confined water and OW certification dive portions of the certification process?I spoke to the Aggressor Fleet administration office this morning. It appears they cannot find any records for that cruise. They are recommending "rinse and repeat" due the lack of records and the amount of time that has passed.
SDI training department did find shop that will redo the OW dives for $600, which is less than $1200. I've also had offers of help from folks on this board. I'm sure we will get their C-cards somehow, but I would strongly suggest to any new student NOT to use the Global Referral program. It has serious problems.
I can’t directly speak to SDI’s Global Referral Program but I know (via my own experience) that PADI’s referral program works perfectly fine.
As other’s have mentioned, the SDI Global Referral Program would have required you to give the Aggressor Instructor the Global Referral Form that would have been filled out and returned to you so you could give it back to the original SDI instructor to complete the SDI cert.

It seems maybe you did not understand how the process works upfront and follow it correctly to be able to complete the certs? Certainly, the original SDI instructor should have informed you of the process - so much fault lies with them!
