Flipkart — od[protected], terrible service from Flipkart

I received a mail and call that my below product marq ac is returning now but i want that please replace this items not return. Because in this ac i took 2 years of amc of rs. 2500/- and rs. 1500/- for installation. If you are returning this product please also refund my above amount (2500+1500 = rs. 4000). Otherwise replace this ac with fresh ac. If you are saying that it is not in stock than i have checked that this ac is available in stock. I already cart 1 pcs in my order list.
