OnePlus India — Strap availability for a OnePlus Band Black

One Plus Band Strap has not been available since 20th October 2021. If you cannot keep a stock of the strap then what is the point of launching the band?
The band strap broke.
I ordered the band on Jan 12, 2021. The order number was: M[protected]Ordered from the app:OnePlus store). I have been checking for strap availability on the website on since 20th October 2021. It's been two months since then. I have not been able to use the band because of this. Either provide a strap or replace my band as the device is of no use to me without a strap.
