HDFC Bank — not receiving otp from hdfc for adding beneficiary

I've not been receiving otps for adding someone as a beneficiary from hdfc since yesterday.

I just moved to nepal and they have no provision for a universal toll free customer care number! Can't get through the so called 'central number' that they have for other countries -'[protected]'

I'm sure one understands how frustrating it is to not be able to speak to anyone! Worse, they have no provision for complaining about otps on their useless 'eva chatbot' system or in their complaints section.

Seems like no one wants to talk otps!!!
