IPv6 on Lumen/CL

We have a circuit on AS209 that was originally provisioned v4-only. I'm now trying to get Lumen to turn v6 up on it. How long does this typically take? I've had a configuration ticket open for nearly 3 biz days now with no movement (or even acknowledgement). For anybody who has gone through this with them, is this unusual or nah? When they do get around to it, what can I expect in terms of how they will prefer to set this up? Separate BGP session running over v6 itself, or modify existing session to have it also carry v6 NLRIs? Thanks, -- Nathan
