Several reasons may explain why you may not have received your invoice within the usual time frame: • Invoices are sent by second class mail (B). They may still be in the post.  • Unfortunately, the post office may sometimes mishandle or lose correspondence. •  We may not have your new address in our records. In any case, if you have been waiting for your invoice for more than 10 days, please contact our Customer Services who will enquire about the origin of the delay and send you a new invoice if necessary. Finally, please note that our GMnet platform and GMapp mobile application allow you to manage your invoices efficiently, quickly and securely. Feel free to contact us if you are interested.
