State Bank Of India [SBI] — Continuous blank calls

I have been getting blank calls from the sbi credit card department since 8:00 am. And i put up the screenshot of the call log and reached out on twitter. They responded to it by saying they will resolve the issue. But right after that and till now, i am still getting the blank calls. They are not stopping it. If it is about the payment, i already sent an email over the sbicard.com as willing to pay an amount of 10k. Yesterday i sent the email and today is this, what is going on? This is mental torture, as i am filing this complaint i received 4 more calls within the span of 2-3mins and it is still the same.
