Can't Get Call Forwarding to Work!

[evie820]

When I enter *72, 72# or 1172 I do not get the two beeps prompting me to enter the forwarding number. I called several times to ask for assistance and they ran a test and said call forwarding is activated on my account. They forwarded my calls on their end and it worked. Then i had to undo it, but when i went back to try again I'm still not getting the prompt to enter the forwarding number. They said to make sure I ended my previous call forward so I keep entering *73 and I get the two beeps confirming I ended it.

What can i do to get this working ??
