no assistance since reporting fault

On the 30/01/2015 reported a fault with our landline via the sms option. Received reply and told the fault would be dealt with within 2days. A whole week passed and still no assistance. Called back a week later and my claim was escalated and I was told I would be called by the technical department. I have still not received any calls nor assistance via a technician coming over and yet I'm being billed constantly and no service being provided. The ***.
