Kanguru Livre XL invoices

Hi,

I’ve sent an e-mail with this question to NOS two weeks ago but haven’t got any answer yet so I will try here since it is urgent.

I use the mobile internet from the Kanguru Livre XL at home and since I’ve been using it working  from home I can reclaim the costs from work but they need an invoice.

I top up the internet through my banking app as you would your phone. Is there any way I can get an invoice for this?

Thanks in advance
