Bajaj Electronics — Unethical behaviour

We have brought vaccum cleaner in the month of october. Store manger Mr. Pradeep said some bed sheets are free as diwali offer for this product. We have called and went to bajaj electronics in boduppal many times to follow up, but there is no response from store manager and he is very rude with the customers when enquiring about the offer. This store is simply bluffing the customers and there is no response from them till date i.e. 06th December'15.
