Dear Aaron,
I would like to remind you that at the time of joining in a hurry people do this mistake, if I am not wrong you might have not asked for an acknowledgement for your certificates from your employer / HR of the company, if the same is correct then how you can prove that your certificates are with them. Both ie., you and your employer are comfortable these many days and you have not reliased and now you quit the job hence the legality came in to picture. If you have acknowledgement then you can proceed legally otherwise some how you have to manage and get those certificates.
