unhone meri complaint resolve karne k badly hame force kiya course buy karne k liye.kai baar call karne k baad b mujhe rply nai diya gaya fake promises kiye gaye. in October month, unke manager ka call aaya regarding payment of course, ie, 150000 for 3 yrs(for grade 4th and 6th).unhone hame emi pay karne k liye kaha, 10000rs dene se b mana kar diya..meri unse argument hone k baad unhone refund se mana kar diya.
