Lenovo IdeaPad gaming Laptop - Scam Fraud

I think I got Scammed. I purchased a laptop on Saturday * December **** at a Lenovo store which cost me **, ***/- as you can see on the bill.

What happened is i told the salesman to give me a ideapad gaming * Gen* AMD R* (part number:- **SB**QJIN) it's current price is **,***/- previously it's price was **,***/- i don't what was the price at the time of purchase but the salesman said the price is **.***/- and that he is giving me a discount. And he gave me a ideapad gaming * **ARH*D* (MTM :- **SB**QJIN) , some guy had it delivered to the store from the warehouse because the salesman said it's not available on the store. I have a video of the guy unboxing the Laptop you can find it in the attachment.I don't know if the product is genuine or not. it says it's price is **,***/- as on Laptop package Box. But on the GST Invoice you can see that the price is **,***.**/- (without GST). It's really confusing.

Now here comes the real problem I don't know why the salesman made an order of some different product (IdeaCentre A*** **.*cms Business Black)[ Model number- FOE***YBIN ] .
Order number is #LEN**********
It's price is **,***/- .
And when i opened the laptop in the Lenovo application it's showing me that my on site Warranty is only ** months left which is hard to believe because I purchased it one day ago.
I don't know what's happening. I'm really worried. I want my money back. Please
