difficult phone forwarding

I have had 2 phone lines with Cox for more than 6 years.  In the past year, it is increasingly difficult to forward the phone line(s) as needed.  One of my phone lines is forwarded (via online forwarding tools)  twice a day ... something I've been doing for the past 4 years.

However, I must allow at least 45 minutes each time to allow the call forwarding to take place.  What happened to the days of it instantly forwarding when requested?  Waiting 45 minutes for the phone to forward is not acceptable - it needs to happen when requested.

I've tried, on more than one occasion, to speak with a Cox representative.  After being told by the rep that "we aren't reporting any problems with call forwarding" (the standard reply for any Cox problem!), the rep went through the prepared "script", which did not help. 

I was then transferred to a "technician" who, again, went through the prepared script.  Oh, this was after I had to repeat still again what I had already discussed with the first Cox rep.  In the end, the technician stated, "we don't even show you have this feature on either of your Cox phone lines" ...... AAAAAAAAAAAAAGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHH!

Funny, I've been paying for it and using it DAILY for the past 6 years!

If I worked as efficiently and reliably as Cox, I'D BE OUT OF A JOB!!!!  Cox - you are not the only game in town.  It would be best if you would pay attention to what YOUR CUSTOMERS (THE PEOPLE WHO PAY YOUR SALARIES!) are saying about the poor quality of service being rendered.
