Sir I ordered One Sandisk 32 gb memory card but it's not working in my mobile so I request for return on refund and it's picked up successfully on 31 march. I also ordered two 128 gb pendrive and both pendrives are received different colour and not same as I ordered..so I request for return on refund and it's picked up successfully on 27 March.. After picked up of 3 items when I asked for refund on 2nd April Amazon said we received incorrect item and clearly denied to refund .But I returned 3 items in original conditions as I received from delivery agent. I have prof.and delivery agent check items carefully before picked up.If items are incorrect then delivery agent could cancel it for picked up then why delivery agent accept this items because I hand over the items in new and original conditions to the delivery agent.I clearly remember that I hand over itmes in new and original conditions I have photo for prof.amazon also block my account. And from 30 March I request till now for refund but Amazon clearly denied to refund. So please Sir help me. Amazon cheat with me.Now I have no money nor products.I added products photos and bills and picked up screen shot. Sir I requested Amazon 10 times for refund for picked up item. But Amazon cheat and denied to refund clearly.. Sir I don't ask for refund for free. As I have already paid moeny and returned picked up 3 items successfully. So please Sir help me to get refund for picked up products. Please help me.. Thank you.
