Hello team,
I hold housing loan from gic under file number mh[protected] and have sent several emails to gic thane branch to provide me provisional certificate and interest deducted so far for investment declaration in my company...
No response seen so far from team..
Emails were sent on 1st, 6th, 7th and 17th may...
Moreover no body receives call when dialled to the office number's.
Due to this i am getting tax applied on my salary every month..
Who is responsible for non-delivering the customer service?
Hope to see quick response...
Regards,
Sanjiv dubey
