The only service charge from SBTPG is the $40 fee for processing the federal tax refund. Since you did not receive your complete federal tax refund after the fees were deducted you need to contact SBTPG or Green Dot Corporation.
For the status of your tax refund you will need to contact the third party processor, Santa Barbara Tax Product Group, using their website - https://www.sbtpg.com/
