Reliance Fresh — related to over billing

Address:

New Delhi, Delhi

When i went to buy some household items from reliance retail store at plot no.1, dwarka city center, sector-13, dwarka, new delhi on 07.04.2018 (Store 6239), i found board at various places in store displaying that "every thing below 5% on mrp everyday". However, when i got bill i was surprised to see that some items are billed on mrp and in some items only 2% discount were given instead of 5%. This is tantamount to cheating with public and unfair trade practice. Such a big name in the industries like reliance should not adopt such type o[censored]nfair practice. Kindly look into it so that such type of mistake should not repeat in future.
