India Post — wrong charges levied

Address:

600033

The w. Mambalam (Postalcolony post master) post office collected from my relatives rs 8/- as penal charges for under stamping.. When contacted he said that for postal card of this size rs 10 is the tariff. On enquiry with po at mylapore before posting we were advised rs 6/- and confirmed again by them when we contacted after we came to know of the different versions of w. Mambalam post master. Further we were advised to verify in the net by the w. Mambalam postmaster.

On verification we found that rs 10 applicable for competition post only.

Please advise post master w. Mambalam to return the extra charges he had collected eroneously.
