Hey @Apratim, welcome to the community! Alex here and I'll be happy to help.
I'm sorry to hear about this, our shipping delays are longer than usual these days. Mostly because of the holiday season that recently just ended, but there's also a shortage of microchips making it harder to obtain these devices.
That being said, the delay for certified pre-owned (CPO) devices is usually up to 2 weeks (unless otherwise specified). I would suggest that you get in touch with our customer service, they'll be able to check your account and see what might be causing this delay.
You can reach out through any of the channels here.
