BSNL, Indore — Charges of Wireless Modem higher than MRP printed

Address:

Indore, Madhya Pradesh

Dear Sir/Madam,

I have recently bought a wireless modem from BSNL week ago.
the printed MRP on the box was Rs1600.00 and in the bill they have charged me Rs 1800.00.
I went to the BSNL office for clarification over excess charges been charged and claimed for refund, but the officials refused to do so and said these are BSNL own charges and do not bother MRP mentioned on the box.
I would like to lodge a complaint, as price charged cannot be above Maximum Retail Price.
Request you to kindly take action against them for such mispricing.
