Coincidently my wife just received her ten year gc in the mail today. It is unclear what has happened in your case as ten year green cards can come via direct consulate filing based on a two year marriage in Thailand or through filing to remove conditions on a two year green card obtained through a a fiancee visa or a spousal visa where the marriage is less than two years old.
I would suggest you join visajourney, a peer based immigration forum and read the guides and find the approriate forum to obtain some further information
Feel free to pm me
