About a week ago I found some commercial software that is closed source using two GPL v2 licensed packages in the binaries. I emailed the company back and forth and they finally agreed that they would release the source code to me. However, they state that they will ship it to me (perfectly fine under GPL) but that the processing time would be around 15 months due to COVID-19 and their engineers working from home. This seems extremely excessive to put source code on a disk and mail it. I assume they are doing this to stall the release of the source code. Is there anything in the GPL license that requires reasonable processing time for releasing the source code? The software has been out for over 2 years at least and has had the two offending packages in it since the beginning. Do I have any options for requesting a reasonable processing time?
Edit: I am located in the US and their main operations are in Norway, I believe.
