Carrier Airconditioning & Refrigeration / Carrierindia.com — product feature mismatch

Dear sir,
It is to bring to your kind notice that i mr. Nirmalya maitra purchased one 1.5 ton air condition from khosla electronics, uttarpara dated april 15 2019.
I was convinced while purchasing that the ac has a special feature i. E. Follow me.
After installing the ac on april 20, 2019 it was noticed that it has no such feature which i was told by the sales executive at time of purchase.
Within 3 days the matter was reported to the shop but they consoled me by stating that they will be taking the issue to their higher authority.
Last week of april i had a talk with the area sales manager and i was told that it is problem of the remote and it can be handled easily within couple of days.
The matter was purposely kept under the carpet and on my continuous pressure the sales executive patched my call with the area sales manager.
I have been chasing them since one month but their sales manager have informed me yesterday that the company has no such feature and it was a printing mistake that company has printed such a special feature for the product’s promotion in the catalogue.
Sir, i feel really cheated and forged at this moment as i paid nearly 3000 inr extra compare to other product (Ac) just because of this mouthwatering feature and they convinced me for one product and sold the other.
Humble request to your kind office to look into the matter and get it resolved as soon as possible and either the product needs to be replaced or else my money to be refunded.
Kindly find the attached documents for supporting my request.
Thanking you.
