Vishal Mega Mart — Dundahera store did not redeem my gift voucher

Address: Gurgaon, Haryana

I am a very enthusiast shopper of Vishal Mega Mart .I spend almost 3-4K every month in vishal. I had shopped on 31.05.2015 at Noida store and Vishal Noida store has given me gift voucher of Rs.500/-. and it was valid for all vishal store. when i gone to Dundahera Gurgaon store they didn't accept the same and said it got expired. while voucher has a written validity till 27th June 2015. I had spend my 2-3 hours to collect my shopping products when i reached to the cash counter he has denied to accept the voucher and said it got expired while there is validity mentioned by noida store manager clearly.and I turned back the voucher and it has mentioned a 90 day validity. i asked to the store manager to help me regards this. He started arguing instead of helping me. his nature was very rude to the customers. he has no answer regards this then he said this voucher has a validity one month without seeing the voucher. Then i said if this voucher has a month validity then why did not your cashier accepting the same. after checking the voucher he said again sir it has validity of one week only.what a funny joke sir i said to the manager. at last i had left all the stuff on cash counter which was around 6000/- rupees and came back to home. Just want to ask you seniors when you didn't know the value of your words why you commits to your customer . And i will never come to the any vishal store in my life or neither i will recommend to other my friends also.
