HDFC Bank — Unwanted calls against loan application

Address: 500008

Website: Hdfcbank.com

I applied for a personal loan online. I got a call for the confirmation and document pickup. I confirmed the time. But the person didn't turn up so far for the document pickup. Instead of that i am getting some spam calls from hdfc atleast 15 times a day, when i pickup the call no one speakes either they put me on hold or disconnects the call. It is happening from last three days. Once i blocked one no they call from a different no. Please look in to the matter on priority. I am also attaching the screenshots of those spam calls for the ref.
