ICICI Direct — change of address

Address:

781015

After 2 visit to icici direct centre in GS Road, Guwahati my correspondence address couldn't get updated though it is already update with my icici savings account( linked to demat acct.)

Each time the officer in charge is asking me different document in different manner. Once they told account statement of axis bank with stamp when provided that again they asked for 3 month Statement + cancelled cheque + one photograph of account holder + self attested PAN card copy. Later I learned from customer care only statement was needed but later were not needed.
I wanted to change address so that my PRAN card linked with icici demand would delivered at my present address. But the officials are harassing repeatedly, which is ultimately forcing me to visit the centre which is 25 km away from my place.
