I-290B Motion to Appeal

Would you be able to prepare a INS I-290B form? I have a B1B2 visa. My I-539 Visa Extension Denial due to No show at Biometrics appointment. I received the notice for the first appointment after the date of the appointment. A second appointment was requested but never received. I've now been here for 3 years receiving life saving cancer treatment for mesothiloma. This was my 4th extension and I have 2 after this waiting to approved. Back Notes: The first notice was delivered after the date of the appointment. I immediately calledINS but this was during COVID.I waited 2 hours to be connected and was told I would receive a phone call back from the scheduling department. After 2 weeks and not receiving a call, I called INS again. I was told by the operator that a second appointment would automatically be scheduled and I would receive a notice. I can prove a second notice was not sent.
