Query: Unfulfilled Promise

I have been waiting for over two weeks to resolve the problem with my APC BE650R's inablility to connect the modem to the phone line. I was told that I would be receiving a replacement withing 5 days, and that I would have an RMA number assigned to return the defective unit. I have yet to receive either. I am stuck with a unit that will not allow a connection to dialup. This is my third and probably final APC product purchase.
