Don't know which is worst, the internet service or the staff

I paid this company for a full month, only for them to switch my internet off after a week. When I call to find out why this is, the idiocy that comes out of these agents' mouth is **********. Nobody can give me a concrete answer, and everyone refers me to chats. When I get on chats, they tell me they can't forward the chat to a supervisor or manager but at the same time, they can answer my query. I have emailed the supervisor, the night before and have since received a reply from them.
