Exams with NO wifi after logging a ticket half a month prior to exams

Im currently writing exams with no wifi AT ALL. Ive logged a ticket on 27/02 and absolutely nothing has been done. They ALWAYS call between 2-3 PM, when i cant answer the phone. I have told them to call in the mornings and they dont. They dont stick to their words and do not call you back. YOU have to call them. They told us they can send a technician to us but we have to pay the call out fee. Im sorry, but we have been paying for a service we havent received and now they expect us to pay the fee for an issue on THEIR side. We got through to them after calling non stop, they still said theyll get back to you, but never do, you still have to call them. Once they do call, they are not at their desk to actually help you. How? Whats the point of the call then? The time we got through to them, they asked for a number on the router(or some box). We told them they have it and they said they, IN FACT, do not have the number. No number is on their system, nothing. Again, how? Arent you supposed to have it? There was apparently a change in some provider and our unit in the complex is the only ones struggling with this problem. They never once thought to inform us about the change. Accelerit was fantastic in the beginning(Jan 2024), but is so terrible now that i would definitely not recommend this company.
