State Bank Of India [SBI] — Harassment Calls and Abusive Messages without following protocols

I needed a clarification with SBI on the settlement offer they provided me during pandemic. They never responded to the concern but just escalating the issue from the past 3 months. Though I made 70% of the amount, they have blocked my card. Inspite of my calls to customer care on the same issue, they started threatening me to pay the remaining amount, though I have been paying the minimum dues.

Upon this, I have been getting harassment calls and abusive messages calling me 'loan defaulter' though I don't fall under that category. They are not following any protocols, they don't know and not willing to understand the customer's issues.
I have mailed to the nodal officer with all the screenshots of the abusive messages. It is so silly that they replied to me telling that there was no such case, though my screenshots were a proof.

I get calls from different numbers and people every time.

I recently tweeted about it, but the issue is still hanging in the air.

And again these harassment calls started.

I have been polite till this time, but I have lost my patience and hence approaching you.

Hope you will resolve this soon.

Thank you,
Sarika
