Croma — cheated on price

Team i bought croma microwave oven from croma janakpuri centre unity one on 26th january 2019.
I bought convection microwave which had price of 8990rs nadeem one of the representative at the time of billing told me that you will pay only 90rs and you will get 2 year extra warranty and one power bank. Total i paid 9090rs.

I went to croma store in dwarka sector 24 today 27 january and i came to know thatt same microwave oven had 10% discount on shown price so i checked my invoice and i was shocked that representative tricked me he did not tell me that microwave has 10 percent discount on that price even i asked him he said no sir but we are giving you offer on my invoice it is clearly given that price was 8990 and i paid 8091 rest 1000rs i paid extra for 3 year warranty and power bank you guys cheated on me i did not want 2 year extra warranty nor power bank but executive said that in 90 rs only you are getting both so i said yes please return my 1000rs extra which your people tricked me and made me pay and did not give6ne complete information on price and discounts you guys have done fraud with me i dont want those two things please take it back and give me my refund that's all i want if you want i can show you invoice please take necessary action and give me my refund cause i dont have extra money to pay for those # things which i don't want and even you tricked me and made me pay it this is all # take action executive name nadeem...
