Manipal Hospital — Invoice of vaccination

On 29th May 2021 Manipal hospital (Old airport branch) did vaccination drive for IDBI Bank employees and it's relatives at Mission road zonal office where I also got my vaccination done, since my company is reimbursing vaccination cost so I requested Alwin thampi senior Business Development Manager in corporate section (responsible for manipal hospital) said we will not give you invoice also told me to Contact IDBI for invoice
When manipal hospital has done vaccination drive, how can IDBI Bank issue Invoice ??
