AVPN circuit physical interface won't come up

We have an AT&T MPLS circuit with CenturyLink/Level 3 as the LEC, at one of our sites. This is our 2nd circuit with AT&T at this site. It is replacing the other AT&T circuit with a lower CIR. Verizon is the primary WAN at this site with AT&T as backup. One of my colleagues was assigned to bring up this new AT&T circuit and decommission the current one. Then he was abruptly laid off. So no one knew the status of the task. Long story short, we are now looking at a circuit that won't come up. Demarc is a Cisco 3600 ME router on a different floor from our equipment. We've re-used the SFPs from our existing working circuit on the demarc and the ASR (our equipment), swapped fiber on both ends, used the same riser port as existing working circuit, tried different ports on the ASR but the ports won't come up. We see -33dbM from provider and they are reporting similar results from us.

Unfortunately, the company has refused to send out any of my colleagues out there. So we have to rely on field support to do the work. This means we have no testers or any other way to validate our end. All they're doing at this point is asking how long they have to pay for 2 circuits! CenturyLink of course see nothing wrong with their side of the circuit.

I'm at my wits end and don't know if there's anything else we can do to determine where the problem lies.
