Is there a template for sending an application to a cellular provider for illegal advertising?

Question

Megaphone

Help to make a template (fish) application for a cellular provider.
The bottom line is that at the conclusion of the contract, of course, the consent to receive advertising was not ticked.
The provider regularly replaces the URL of the page that I open with my page with advertising, while the page being opened is lost, which is annoying
. I need an application template for them, I see a violation of the law on advertising, I did not agree to it, the law on communication, I didn't get the service I wanted.
