Remove Telus announce message, Billing information unavailable

I have been trying to change the announce greeting on my cordless phone/answering machine.  I successfully have re-recorded the message but each time someone calls they receive the old message.  I was feeling the phone was faulty.  But after checking the internet it seems that the message has been saved on the Telus server and not on the machine.  How do I get rid of this message?  I am changing to another provider.  Will this finally get rid of the info?

 I am changing to Shaw/Rogers because I have been unable to get my bills online.  I have spent over 10 hrs on calls with agents in the Philippines.  Each time I call they say the issue is resolved.  But when I open my Telus account online I receive the same message,  “we are sorry but we are unable to locate your billing information.  Try again later”. This has been over a month.

So disappointing to see a company that once great to become an embarrassment to Canadians.  The worst service imaginable!
