@ARP_ASUS I requested for pick up and drop repair service 2 days ago, but there's no update after that, every time I contact your support team they say that the PUR team will call you in the next 24 hours.

Is it picked up?

[rahulmehta942]

@ARP_ASUS No, they call me at night time after every few days and tell me that my address is partial, I confirm the address with them and then this cycle continues. This is the same address to which Flipkart delivered my phone how come now you have an issue with it at the time of pickup?
