求助法律专家:

How to sue a company, in the course of carrying on a regulated activity in contravention of the general prohibition, under Section 26 of FSMA, to get back the money I paid under the agreement and compensation for any loss I sustained.

How to sue the Financial Service Authority for regulatory breakdown?

这家公司已经搬家，信无法寄到，我想直接起诉这家公司先把文件递上去（一旦这家公司宣布破产我投资的钱就拿不回来了），同时想告 the FSA 渎职。想自己按照程序走不想找律师。

请那位清楚金融投资方面法规的大侠帮助，谢谢先。
