Citibank — No due Certificate not received even after 8 months

Hi,

My Credit Card number is [protected]

I had cleared my dues in November 2020. However, after repeated followups for 2 months with the collection agent, I did not receive my No- Due Certificate. I tried reaching out via customer care number- there was no option to connect with anyone or register my request. I could only talk to the IVR that said that it has no information regarding a closed account obviously. I also tried dropping multiple mails- but i did not receive any responses whatsoever regarding my issue. This is utterly disappointing.

There is no way I can request for the No Due certificate in any of the citibank channel directly. How long should i keep following up for a basic deliverable from your end? here's my contact, should there be any more details required from my end- [protected]
