Punjab National Bank [PNB] — No one to take calls for days on end

Address:	Hyderabad, Andhra Pradesh, 500028
Website:	bank

My mother K.Rajyalakshmi has a pension account at the Punjab National Bank-2nd Lancer Branch at Nanal Nagar, Mehdipatnam-Hyderabad
We live away from Hyderabad in a different city and I am trying to call the Bank Branch for the past 14 days but either only an attender answers the phone and puts us off or no one takes the call.
Nationalized banks have a big responsibility to attend to the customers as it is OUR money that is with them and they make this to be a favour to US only.We are not taking favors from them but instead their jobs are due to us customers.
The telephone nos of the bank branch are :

This needs to be pulled up by the bank authorities.
Yesterday I even sent a mail to them as no one was attending to the telephone for days on end.
This is serious and needs to be put into place.
