I'm having a IDFC 10k Savings account since October-2021, and by February I received a pre-approved offer for first millennia with limit of just 40k. Since, it was my first ever unsecured credit card, I accepted that offer and proceeded.
I want to share my personal experience here-
Once I tried to ask my CIBIL related queries via mail. I remember, I didn't get any proper response and my case somehow got escalated that I received a call from one of their upper level team executive (I dont know what exact position she told me, but some kinda senior level) . And while talking to her, I got to know that she's got some serious level of knowledge based on her answers to my queries. I just honestly told her that I was unaware of the enquiries being made with the applications for Flipkart pay later and OlaMoney postpaid+. Also after this enquiry related queries, I asked in general in a very unorthodox way related to my credit card scene. She told me, at this time bank is not providing any kind of limit or variant upgrades to existing customers and is currently working on to implement these features to their card services. She also advised me to utilize as max as I can, even should go to the fullest, to be eligible for limit upgrade as it will be a key-point for limit upgrade. But for card variant upgrade she told me that currently no one from their team has any idea regarding the same.
I want to add that, Even after explaining how I've given consent for the credit enquiries with Flipkart and Ola, She actually unexpectedly helped me with the rectification of these enquiries which she told me will be considered as an exceptional case (God bless her).
It is actually my personal decision to trust her with that max utilization for limit upgrade thing, as I believe that she wont be giving any false information intentionally, Because she was in no hurry to close my case and and hang up the call, instead she was so calm and so understandable like a teacher, she kept listening & answered my each and every query even when she wasn't supposed to; I guess, cause primarily this was not anyhow related to the request I raised with the email. I've never ever experienced such kinda customer service from any other bank or even a company I'd say.
I wish we get to see more of such people in customer service.
P.S. - Trust me, usually, I just do not butter things up and also hate typing this long but I guess its worth it.
