ICICI Bank — did not send fastag neither returned amount since 9th dec 2019

Dear Sir, I applied for a Fastag on 9th Dec 2019 and uploaded the required document. I received a SMS on 9th dec 2019, itself saying Fastag ID is 11847956 and it is active. However there was no Fastag delivered till date. Both the Fastag helpdesk numbers are useless as no one respond to my call . The music goes on and on and IVR says some executive will be attending shortly. After few rounds everything stops and line goes dead. Assuming it may be some technical problem, I made more than 15 /20 calls on different days and different times but no use. I called ICICI customer care no for banking operation but the agent their expressed his inability to help as they do not have any information pertaining to Fastag. When I informed him no one responding to Fastag helpdesk number he advised me to go to home branch personally.
I made few trips to Sahakara Nagara (Bangalore-92) which is my home branch, but the manger there could not help me further after few calls to their internal staff.
Even when I complained using ICICI procedure, they also directed me to Fastag Helpdek without checking that it is usable.
Whomsoever I contacted in ICICI either to send me Fastag or atleast return my money it goes in deaf ears. All are putting me in circles and not thinking the ethical part how such bank not returning the amount neither sending me Fastag.
Very frustrating experience, not sure whether I still chase these people or just forget about Rs499 and close all my account with ICICI.
I lost my confidence considering the fact next if they do not return my FD money and put me in circles like above where should I go then. Lost time effort and money with this kind of bad customer service.
