Reliance Trends — Offer was not availed

Address:

Khata 326, plot 2750, near bazar India, Madhubani 847211

There was offer on purchase over 8000, my total bill was 6500, he told there is offer for purchase over 5000+. When i went to offer counter they told there is offer on purchase over 8000, so I purchased for 1500, then total bill became 8000+ when i went to offer counter they told there should be only one bill of 8000+, so I can't avail offer.

This kind of miscommunication should will not be allowed.
