Relocation of Russian account

Hello! I have the Norton account registered in Russia. Norton is obviously not working with Russia now. But the thing is, I have relocated to Serbia some time ago, which I can prove if needed. I have also changed account location in account info settings. But I still can't prolong my subscription. How can I fix this? Of course, I can just create a new account, located in Serbia, but I would like to keep my old one, if possible.
