Hi Vijay! Your return pick up for RT42364328 is scheduled today. Please collect the acknowledgement slip once you handover the return package. For details click bit.ly/37ook6p

I've ordered footwear and got delivered on Monday.products are unfit and initiated return right after receiving. Later, for straight days i used to get messages that pickup partner tried to pickup but didn't work out. The thing is i didn't receive not even one call from pick-up guy since then. Then i contacted customer support and after trying many times but no one contact
What kind of customer support is this??? Again i requested for return and hoping it will workout at least this time. Or else I'll take this to next level. (Sent by mail but still I waiting)
