Times Of India — Vender's mischief

I have made annual subscription to Times of India's Chennai edition with effect from November 01, 2014.My subscription No. is [protected].The vender's boys deliver the paper regularly, but sometimes they deliver Hindu paper instead of Times of India.I have pointed this deficiency in service to the authorised vender on his mobile. He had assured me to make amends and deliver the missed copies of Times of India on two occassions, but all in vain.Even today he did not fulfill his promise!
