Unblock Team viewer ID

Dear Team

I am not a licensed user of team viewer, my trial version of team viewer is already over and now my id is blocked for further use. I am in need of the software for a month and a half as I am working from home due to my medical condition.  I have contacted the customer support and they denied to accept the payment on monthly basis. I would really appreciate a positive solution to my problem.

Best Regards

Aarti
