Bad Customer Service and connection

Firstly the company has bad customer service with heartbreaking turnaround time. For the past 3 weeks we have been having issues with connection between 1am and 8:15am, it goes offline daily without any consultation. They claim they are running maintenance on their towers which hasn't been fruitful, we pay for this service and we don't have any agreement of them capping us, some of us work through the night and it is a challenge without the internet service which we are paying full amount for. Im extremely disappointed because I even struggled with paying them their monthly because their consultants have incompetency issues. Im really disgusted by their services, and I know about 5 people who are impacted by this.
