Terrible service

Worse service I've ever received from a company. Paid for installation and the premium package installation and equipment was done on Monday. The technicians said that everything is connected and that they need to access some room downstairs but they didn't have the key for it but they will get it sorted. We are now on Thursday and I've heard absolutely nothing and still no internet. I've called your call centre so many times and they just say they will escalate. Timothy the manager was rude and condescending and I would like him escalated as well. I need my internet to be connected and activated.
