Illogical client service with bad line issues

Absolutely furious at Afrihost service!!! We pay a premium for apparent fast line speeds and wifi services and run our business from this and when they have issues with their speeds and lines it all of a sudden becomes my problem to solve. My line has been dropping intermittently for over a week now making it difficult to design in my programs and RUN MY BUSINESS! I get told today I need to go purchase a piece of equipment that allows me to plug the cable into my laptop else they can't help me. ARE YOU FREAKING KIDDING ME 🤬 When did your ridiculous service issues become my problem to solve? Let alone forking out time and money out of my schedule (I must just drop everything now and run to the store for a cable) to see if PERHAPS that may be the issue? You cannot be serious with this.
