Firstly i made a big mistake by choosing amazon for purchasing lenovo zuk z1 - mobile.
I had a very bad/worst experience from amazon customer care executives.
My refund money of rs 10990=00 was deposited in gift card of amazone india instead of given registered icici bank a/c no.& for this big mistake amazon customer care exec. was given all types of different stories & they forcefully putting on my shoulder that i had given option for refund money into a gift card & for this they don't have any proof with them or in there system also that i have choose a gift card option or i told them to put my refund money into gift card. amazon exec. blindly made such foolish statement.
I am getting frustrated/very nervous by telling amazon exec. repetitively that i have not choose gift card option for refund of my money & for refund of my money i updated my icici bank details on 07th nov.2016 at 10.25 p. m & my refund was deposited on 15th nov.2016 at 8.23 am.
Even though i don't know also that gift card option is available for refund of money at amazone
