Can't Buy Zoom Phone

[niyamat]

I want to purchase the Zoom Phone Unlimited US & Canada option. However, when I proceed to the checkout, the verification section asks for a phone number to verify. Unfortunately, my country, Bangladesh, is not listed in the dropdown menu. Strangely, Afghanistan is included, but not Bangladesh. Due to this, I am unable to complete the verification process and finalize my purchase.

I have attached a screenshot for your reference. Please take a look and let me know how I can resolve this issue.
