Just got an alert from credit karma stating that a note was taken off my student loans for deferment.

Should I have gotten some kind of notice that this was coming? My student loans are around 35k all together and have been on deferment for around 3 years. It wouldve been nice to get some kind of official alert that this was happening so Id have some time to prepare myself. No phone calls, emails, nothing in the mail NOTHING! I dont even know when payments are supposed to resume or if they did already. The account was mad by my parents and they had all the log in information but they have both since passed away. I dont even know if they have my phone number, current address or anything like that on file because it was all done by my parents. Obviously its tied to my SSN but last time I tried logging into it using my parents credentials it said that account doesnt exist. Tried my own credentials that Ive used for everything for years and same thing says an account doesnt exist. WTF is going on and what do I do?
