Trending @Accenture; Accenture not issuing Salesforce vouchers.

Folks I have applied for salesforce admin voucher on April 10. Still it is not assigned to me. Approved by manager and exam team but since vouchers are not available in stock they are not issuing.

Followed up multiple times when will voucher stock arise but they are saying they don't know when will voucher will procured.

Any reason why vouchers are getting delayed?
