Noise and Another Conservation when making phone call

[jeff_s1]

I have both noise and can hear another conversation when making a call.  Reported on 10/15/12.  Technician came 10/20/12 and told me that he hears problem at main box.  Told me problem is in underground cable and will report it and a cable crew would fix it by 10/23/12.  It has not been fixed.  On 11/9/12 called Verizon and was told do not know whne it will be fixed (not even scheduled).  How can I escalate this problem and get it resolved.
