Cantabil — have a complaint about your garments scheme

M not satisfied with your service as your outlet gives me only 2 free on purchasing 3. But as your offer says buy 3 get 5. I went to other showrooms like peter england, louis phillips, puma they give the offer buy 3 get 3 means on totality 6. I have a snap of your add from where i purchased from pune near city pride. I want compensation as you are did the fraud with me as i have the proof. If not revert back from your side within a day i will file a case against cantabile.
