Conflict between service providers, now affecting ME

Linteg has been extremely unhelpful as a service provider. I have been without a connection for two weeks now...my TV and laptop are completely unusable, and only my phone remains connected. GAIA claims they are not responsible and insists that Linteg should resolve the issue, while Linteg, in turn, denies responsibility and refuses to take action. Frankly, I don’t care which of the two companies is at fault—I just want my service restored. I am paying for a connection I haven’t had for two weeks, and this lack of accountability is unacceptable.
