Ferns N Petals — charging price which is more than double of MRP

Address:

Ghaziabad, Uttar Pradesh

I have purchased "gopaljee thandai 500gms pack" from ferns n petals few days back...mrp printed on the pack is Rs 210 only and the price they charged from me for this pack is Rs 549. They have nowhere mentioned in product description that they are charging more than double amount from customer. But when i raised complaint they said we are selling all our product at more than double amont and we even dont accept any return or exchange. They are making fool of customer and they say that we dont care...i want to file a strict consumer complaint against them.. Please take strict action against them.
