Hi Soundaryan,
Thank you for contacting the Microsoft Community.
I understand that you have an inquiry about your voucher code, and I am aware of the importance of having accurate information. Allow me to provide you with all the necessary information you require.
For me to proceed in checking the details of your discount specifics, kindly provide the required details through the private message I initiated.
Meanwhile, if the discount you'll be utilizing is a company discount, please coordinate with the ESI Support team as they are the ones who handle company discounts in which they have the capability to check the details of your discount. Kindly refer to their contact details below:

I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages. Thank you.
Kind Regards,
