Reliance Fresh — issue with product mrp cost

Address:

Kolkata, West Bengal, 700136

I purchased Amul spray 500gm, 7pcs on 9th Dec 2017.Bill attached. On the product MRP is Rs175.But in bill it is mentioned MR Rs188 and our price Rs175. It shows that Reliance fresh is giving me discount of Rs13. Actually it is not. There is no MRP OF Rs188 on that product. They are making customers fool like this. I guess they are doing same in all bills where customer are not escalating it properly. I want to stop such issues. And want expiation why there is mistake with bill n product MRP. I need my money back due to such issue. My contact number is[protected]
