Honestly you are lucky to have gotten anything at all. Ive seen horror stories of people never receiving tens of thousands. I saw someone say if you receive the money it is you agreeing that's all that is owed to you.
But don't have your bank return the rest because they will just try to absorb it all ( in my opinion based on what Ive seen and what I'm currently going through). Don't spend any of the money and make contact with the financial group to try and get them to correct it. Who sent you the funds? SBTPG?
