Reliance Fresh — Product charges more than MRP

Address:

Ramanthapur Hyderabad

Hi,
I am almost a regular customer of reliance fresh since 2 years and always been happy with the service by reliance fresh till now.
But today I am so surprised that rs5 charges more than MRP. How it is possible?
I bought Patanjali mustard oil 1 litre bottle. In that the MRP is rs-190, but in the bill they charge 195.
I never cross checked my bill, but today it’s kind of shocking for me, and the attitude towards Reliance fresh is changed totally.
Please take necessary action on this regard.
