Bajaj Electronics — Unethical Behavior of the Sales Executive.

We happened to buy an Air Conditioner from Bajaj Electronics, A.S. Rao Nagar Branch. It was billed for Rs.32k. The next day, the executive who showed us the product, called me and asked me to pay Rs.700 extra as the Product charges were hiked( which is what he said) and when I asked why didn't he do it correct the first time, he was saying that "you are going to pay from your pocket, so why the fuzz".
I would request the concerned persons to take appropriate actions against such executives, or else this might spoil the image of Bajaj Electronics.
I do have the recording of what that executive spoke, unfortunately I am not able to attach here.
