(The Seller: Infotrade Impex has already shipped your order on 22-May-2018 via courier:Delhivery. Expected delivery date and time 08 PM,23-May2018)
but i could not recieve my order then i connect a call to customer care excutive and they kept me on the IVR Script for 45 minutes after that they attent my call,
i told the customer care excutive that i could not recive my order yet,he replied me, " your order will be delivered at 24-May-2018 till evening.
And Again at 24-May-2018 i check my deliver order status then i saw “your order is out of delivery”.One more time i connect a call to customer care excutive
and this timme they kept me on the IVR Script for One hour after that a excutive answer my call i have all call records and he told me your order will be deliver tomorrow(25-May-2018) till evening.
