Voicemail Indicator Light never worked

[ABN1]

I just recently had FIOS Voice/TV/Internet installed and have been very happy with all service, but I've have a problem since day one. 

The message indicator light has never worked on our phones.  I've called support (a week ago) and went through a number of things with the support agent but nothing was fixed.  Afterwards, the agent said they were going to write up a ticket and escalate the issue and I should hear back within 24 hours.  Now it's over a week and I haven't heard from anyone and the message light still doesn't work.
