Morestore — manager behaviour

Dear team, i'm here to say the bad experience at your more store, nizampet hyderabad yesterday. We came for an exchange of a gyeser as it's a defective piece. The manager and staff surrounded us and not willing to replace it. Im a customer from past 3 years. No one will tolerate this. We complained to police as well if there no proper action on this will sue a case and even to consumer forum. I never seen such a rude behaviour anywhere.
