Delayed Delivery of Nvidia Jetson Nano Super

I have ordered Nvidia Jetson Nano Super in India from TannaTechbiz #1000004775 on 23rd Jan.
But my order is delayed. Every time they move the delivery date even they are not so responsive. Moreover the delay is not expected. The promise is shifting every month. Also not updates from seller side. I just have to follow-up with there slow responsive system.

There is no certainty about availability, Provide a realistic timeline instead of changing the date every few weeks.

TannaTechbiz. When will my order actually arrive?

This is purely inappropriate to let the customer waiting for so long when they already have paid in advance and no updates has been provided to them.
