Kalyan Jewellers — got cheated of not getting gift that company (kalyan jewellers) assured in their advertisement

Address: 110088

Went to kalyan jewellers (Karol bagh) on 30/12/18, bought gold jewellery cost of rs. 38000, after bill payment they started to offer coffee for us (They mean only customers who pay cash).. Whatever we just asked about gift that they assured though their advertisement starring (Manju warrior).. They were telling that offer is applied only for south and we won't offer any gifts! Just thought for a moment whether i'm still standing in kalyan!! Thinks of a son with two father!! Fraud practice..!
