My right to purchase was voilated

Location/place: Ghaziabad

Name of company/service: Easy day

Dear Sir,

Today I went to purchase cups on discount from easyday store at mahagun vaishali ghaziabad for my staff. I wanted to purchase around 72 soup cups for my staff of 12 @6 cups each. I was stopped and easyday people did not bill it, they said that they will bill only four cups each in one bill. then I called all the staff to get it billed but when they saw our people they said that they will make only 6 bills.

1. If the are restricting the customer in purchasing the no of items on discount, than it becomes their duty to mention it.
2. Can a store legally refuse a customer anything on sale when the customer is ready to pay legally. If yes than at every item it should be mentioned that each customer can buy the mentioned no. of pieces.
3 If their is a restriction of no. of pieces each customer can buy than in dewali season also retail stores should be restricted to sale the no. of pieces.
4.It is a direct insult to the Customer and consumer rights.
5. My rights to purchase is violated.
6. In my own country I am stopped form purchasing goods.
