Kabel installation

I signed an internet contract at the end of November. The sales representative offered to connect me to a 1000 Mbps plan. A technician came to connect the internet in the apartment and said that there is no reception inside the apartment, only outside, and approval is needed from the landlord. My landlord did not agree to drill in the apartment to perform the connection and said I should connect to the internet at a regular speed. I went to the branch and requested to change the contract to regular internet. The representatives said it's not possible and that we don't need to worry about approvals from the landlord – only they do. On December 15th, another technician was supposed to come but did not show up. After speaking with customer service, they said they would schedule another technician for us but noted that we are responsible for obtaining approval from the landlord to perform the connection. They scheduled a technician for tomorrow (December 20th), but we received a message that the appointment has been postponed to January 15th. From November 24th until January 15th without internet? The phone service isn't helping and isn't providing solutions. We want to cancel the contract and make a new one for regular internet. How can we do this?

Thank You.
