Not cleared term & conditions during purchasing

I purchased 1pc formal pant at cost of 2500 Rs & 1 pcs formal shirt at cost of 3700 which was discounted of 25% at 5000 Rs. So my total billing was 6300 Rs. Before shopping I asked to salesman for any offer. He said at shopping of 5000 Rs. You will get a kit at FOC. There was no terms and conditions in detail & salesman also didn’t clear me. He just said at shopping of 5000 Rs will get a kit. After clearing the bill of 6300. He refused to give me that kit. Then I asked him for refusing. He said this offer is only at purchasing of fresh arrivals at 5000 Rs. But you purchased the discounted shirt. So this offer is not applicable for you.

So I m feeling very bad for this kind of make me fool & conceal the details. So I expect from supplier to do need full for me.

Thanks /Regards
