I purchased around 8 items today and 2 of them were in offer i. E. Buy 2 get one free.
But the staff never mentioned which one is free
I even asked them on the cash counter he mentioned nothing is on offer. We'll after spending around one hour in the store i thought ihv mistaken by that offer and hence couldn't say anything further to the cashier.
The bill worth 6900 was done.
Later when i again chked at the place i picked those 2 items i saw that the same offer was mentioned.
Now after talking to everyone including the manager i was told that i had to pick the 3rd item which had the similar offer and that could be free

1. Shouldn't this been known to cashier?

After arguing i was given a gate pass and told that i can pick the free one.
While picking i again asked if seriously it will be free and i was told yes.
I picked a jeans worth rs1600.
Again at the counter i was asked to pay 700 extra.

Why? Coz that was the highest of all 3.

2. Shouldn't this also been told to me? I was told it will be absolutely free.

Now it was like 2 hrs in the store. Waste of money and waste of time.

What is expected for a customer to just stay cool?
Why is the system not having the relevant checks as when 2 r scanned it shud promt that the customer should pick the 3rd one?

Finally i could not take the benefit of the offer.
What is the use of such offer when the customer is bullied in this manner?
The entire offer is to be explained when you make some noise?
I lost the benefit
I lost the trust
I wasted my time... Rubbish pantaloons
