While the company claimed they were not aware of the switch, they seemed to think the owner of the account was aware, and the company is banning him and calling for him to be prosecuted, too.
"We are shocked and appalled by this behavior, and there is absolutely no tolerance for it on Grubhub," a company spokesperson told the broadcaster.
"We confirmed the individual charged with this crime was not a Grubhub driver and has never been contracted with us. He was using another contracted driver's account without Grubhub’s permission or knowledge, which is a fraudulent misuse of our platform."
"We banned the driver permanently from our platform and support efforts to prosecute both individuals to the full extent of the law."
The company added it runs rigorous background and vehicle checks before contracting any driver, and is continuously reviewing policy to try to combat fraud and ensure customer safety.
A very grateful Rick Block said hundreds of people had been out looking for the puppy before they figured out she had been snatched.
He had initially offered a $5,000 reward for her safe return; he said he now plans to donate this to the Jacksonville Beach police lodge as a way of saying thank you.
