30 day clause - Part of the communication?

When people depend on Internet services for studies, it is a critical service. I reported that my Internet services was down and everyone I spoke to promised to phone me back. Well, I am still waiting. A week later. After reporting the fault on the Openserve Connect App, Openserve came through the next day and resolved the issue. So, at the end of the day, it was a fault on the equipment, not Wondernet. Wondernet is at fault for not communicating. Even the Call center supervisor Sello, does not return your messages, after you have given him the information you require. Angelo responded to my email and tried to assist, but the service was restored already. I have signed up with a new service provider and I have to wait for 30 days for the line to be released. However, in the Wondernet T&C's there is no 30 days clause.
