Big Bazaar / Futurebazaar / Future Retail / Hometown — not get the free goods after purchase in offer period

Address: Visakhapatnam, Andhra Pradesh, 530046

On dated 26/01/19 i purchased a clean mate disinfectant solution with billing amount of 320 however there is an offer of buy one get one free after getting confirmation from concern executive i take one bottle of floor cleaner of 2 ltrs. But the bill i given was 320. Moreover neither they gave me 1 bottle free or deduct the amount of 1 bottle. After communicating with customer care the # fellow is telling me that come with bill we will search in camera and further steps shall be taken.
I came to vizag for 2 days and returned back to native which is 200 km from vizag.
This type of cheating is not acceptable.
