Super weird that we have the same deadline... I'm trying to figure out how to send the explanation letter then. Pls update me on any account changes you'll see. Thanks for the insight!I guess webform. Just checked my portal again, and interestingly I have the 17th of October as the deadline too - weird. I wonder if it's a glitch. For me it shows the CSQ as submitted on GCKey. Having said that I will keep chasing if I owe them anything else - although I doubt it because everything has been completed for me, just waiting for next steps (been waiting for two months).
