I would be surprised if Azure doesn't waive or reduce this bill dramatically. Something similar happened to me with AWS. I had a simple file upload service where files would expire if they hadn't been accessed in 24 hours. Someone started using it to upload music and videos. I ended up with a high bandwidth bill on Amazon S3. I reached out and explained what happened, they waived the costs entirely (to the tune of $5000).
