Saravana Stores — product return

Address:

Porur, Chennai, Tamil Nadu, 600125

Dear sir/madam,

I purchased milton bottle from porur sarvana store on 16th nov. 2019 and it was mixed with 1000 ml bottle in store. So i picked one which was 600 ml. And thought that it is 1000 ml. When i filled water at home then i found that capacity of bottle was less. So next day i went to store for exchange and was asking for 1000 ml. But store did not give me exchange. Kindly provide exchange for the bottle. I want 1000 ml. Not 600ml.
