Some license issue with a bot I ordered

 
I ordered a freelance work (bot) and two weeks after I paid it just stopped working because some license issue. The developer ignores my messages. I don't what to do.

Haven't you received the source code?

You will be required to submit such cases to the MQ Service Desk.

no licenses. The developer himself wrote to make the Robot stop working. You should always request the source code
