I'm very unsure on how to do so...I've read many times about people reaching out to their reps, but I never really understood how that is done...do I just show up at their office and ask for help?! 
At the same time I am trying to think that VJ just provides a small perspective of a bigger picture and that maybe my situation is not that unsual...when I went for my interview there were around 80 people waiting for their cerimony, maybe some of them waited this long too...Idk, trying to keep positive...but I am pretty frustrated. Anyway, thank you guys for reading and answering.

@AliaAlia congrats!!!! 
 
What is the date of the update "change of address"? Yesterday I called USCIS to check on my case (still pending) and the latest thing they could see was a "change of address". I did change my address but more than 3 months ago and the update they saw was dated 06/26...  :-( 

So here's how this is done for future reference.
1. After I became a US citizen and attended the oath ceremony, the I-90 Green Card 10 year renewal application I had filed 5 months earlier was still pending. (For some inexplicable reason it only took 68 days from filing my N-400 to attending the oath ceremony to become a citizen)
2. I then contacted USCIS via the 'contact us' button in my myuscis.dhs.gov online account and they advised me to send a letter to the following USCIS office:
 
US Citizenship & Immigration Service
Potomac Service Center
Stop 2425
Arlington
VA 20598-2425
 
3. The letter referenced by I-90 Receipt number (an IOE number in this case as I had applied online) and requested that the USCIS withdraw the application as it was no longer needed in view of the fact that I am now a US citizen.
4. Just under a month after I mailed the letter, I received a notification text/email from my myuscis.dhs.gov account confirming that the application had been withdrawn. The USCIS letter also confirmed that no refund would be made of the biometrics or application fees I had paid (not bothered about that and wasn't expecting it). It also explains that an application can be withdrawn at any point before a decision is made on it however the application cannot be re-activated and if I need the green card renewed in the future, I will have to apply again.
5. The case status of my I-90 application now shows as 'Withdrawn' on my online USCIS account as below:
Withdrawal Acknowledgement Notice Was Sent
On May xx, 2017, we received your request to withdraw your Form I-90, Application to Replace Permanent Resident Card , Receipt Number IOExxxxxxx, and completed our review. We mailed you a Withdrawal Acknowledgment Notice. If you do not receive your Withdrawal Acknowledgment Notice by June xx, 2017, please go to www.uscis.gov/e-request to request a copy of the notice.
 

Anybody N400/I751 combo pending from Chicago here? 

@kdg Were you an online filer or paper filer ? Also, did you have an I-751 pending ? Congrats on your approval either way
 

@AK_2014 - Fingers crossed and praying. That is quite a nightmare! 
 
We have also applied for N400 with I-751 pending. Is it fairly typical for N400 interviews to get denied when I751 is pending? I have read on some forums that they sometimes complete the two together. 

@mrs thb thank you!
