HDFC Bank — No service from phone no[protected]

Address:

400029

Called Up the above mentioned Number at least 20 times during
the last 3 days and every time I did that the executive at that
end just kept disconnecting the line. He or She just hung up.
Very frustrating. This I did because I got an email from HDFC
Life promoting your New Immediate Annuity Plan.
Is your staff or your outsourcing call centre not ready to
provide service.
