[Resolved]  Lenovo — Defective Mobile A536

I purchased Lenovo smart phone A536 in the month of September 2014 through your online shop. The product was delayed for about 20days. On tracking the product on your website, it was informed that product was first called back from Delhi to Mumbai, when I asked for reason of calling back product; your officer from Mumbai informed that defective product was shipped. Then after 10 days I received product. I think defective set was again delivered to me. From very beginning product’s WIFI was not working. Yesterday I got chance from my busy schedule to visit your service center and today they informed me that board of phone is to be replaced and it will take about 7 days. I want know why company is selling defective sets? Why should I wait for repair? Why defective set was delivered? Why set will not be swapped with new hand set? Wants Lenovo's answer on following points: You have not replied all the concerns raised in the trailing. Why replacement of set is not possible ? This set was defective from very first day ? The battery backup is very low? I am without phone since last 9 days ? What is my fault? Why have not you checked before selling this defective set? I need replacement with new set? I have been cheated and who will compensate me for my all this trouble without my fault
