Oh no... You might want to contact a specialist in order to have it resent.
Here's a tip, You might want to enroll to Paperless Billing and register to My Account (GLOBE) so that you can view your bills a few days after your cut-off.
Oh, and you can also download the GServices App for your Android or iOS device.
If you're worried about having no proof when paying your bill; no worries! All you need to do is provide your account number, and you should be able to pay your bills in any payment center.
Hope this helps.
