RBL Bank — Unable to add or register credit card for past 4 months

Address:	RBL bank Chennai.
Website:	www.rblbank.com

I am a credit card holder with RBL bank, I am feeling so shameful for being a customer with this RBL. Its one of the Worst banking services, i had never saw in my life . I have an grievance since June 2020, regarding this i had raised around 52 complaints via Emails and over the call i spoke with them around 37 times for a single issue, the issue is created by them only .
Solely they had downgraded my credit card, while asking for reason they agreed their backend had done by mistake . After that they had looted my hard earned rewards points from my rewards portal, when i enquiring this they said all done by some mistake, due to Covid 19 they were unable to work faster . They said soon they will resolve it, as it confirmed on August 2020.
As of now i am writing, following up my issues, escalating the issue with thier Principal and Regional Nodal officers, you will be shocked their Nodal officers not have an habit of reading and replying back to customer grievances .
I had never saw such a kind of Nodal officers, i doubt whether they have a habit of seeing emails or not, almost 6 months those very responsible Nodal officers doesn't have time to read emails about customer grievances . Very worst Nodal officers i never saw such a nodal officers anywhere .
Even the poor courier vendor services has the habit of reading the emails and replying back, but RBL bank Nodal were extraordinary persons, they were so busy with their family and personal life . So i stopped using this RBL bank services, i advise you guys do not use any of the products from RBL bank and do not wish to get a account with Ratnakar Bank Limited.
Very Worst bank all over the world, i had never saw such an bank and Nodal officers, hope i will have a chance to meet such kind of persons in other aspects of my life .
I am being shamefull to be an RBK card holder, worst bank Worster Worstest !!!
