UniverCell Show Room — Samsung Galaxy cheated

Address:

Bangalore, Karnataka

Univercell showroom is selling mobile phones by advertising 0% interest/15% cash back on samsung mobile phone. when i bought the mobile phone,
they told the credit card is not accepted for EMI option. But when i called customer care of my credit card department, it must be accepted. They cheated. I didnot get my 0% interest. I had to pay my payment. when i asked the manager of showroom, what is done is done. it cannot be undone...........please be aware don't go to Univercell showroom in bangalore
