Vishal Mega Mart — forced to buy instead to repaying cash

Address:

160020

I did shopping from vishal mega mart mohali on 15 th dec 20118 & my bill no. Is[protected]. I felt glad to be a part of vishal mega mart family. Next day 16 dec 2018 to replace one item of cost (Rs 199) i again went to vishal mega mart mohali. I liked one more item of cost (Rs 149). I was asked to generate a slip form entry gate so i did. Till then i was of the impression that i will get my rs 50 back as cash. I went to cash counter but i was denied to get back my money.
It was told to me that the slip which was generated is not eligible to get my money back.
I requested mr. Ghansham das who actually generated that slip please change this slip as i want my rs. 50 back. But he denied he said take something of rs 50 rupee value but you will not get cash of rs 50.
* on every bill of vishal megamart ot is printed that cash will be given in case of return.

Please let me know if any this issue can be resolved or i should proceed with any legal option.
Thanks
