Hongkong & Shanghai Banking Corporation [Hsbc] — e-firc issue

Address:

Rajkot, Gujarat, 360001

My client has transferred the gbp from his hsbc uk to my union bank of india branch.in this case hsbc india became mediator and converted gbp to inr and did neft in my union bank account.
Now i need e-firc to submit.
I called their customer care executive many times and they asked to visit nearest branch which is 250 km away.
I specially visited the branch and they told me to visit mumbai which is 800 km away.
On their website i cant file a complain. They just note down my request and called me without any updates.
Their phone banking executives do not any idea about what is firc and who can provide.
All the time same answer - visit nearest branch.
At last i get firc mail id but they replied in encrypted mail which is not able to open by union bank it team.
Really worst service by hsbc bank
