NOC emails get a generic replying saying they are investigating on loop, NOC phone number seems to be disconnected and their general phone number won't do anything without a service ID. How about you post the prefix in question that you see looping and then others can maybe look deeper into it. Did you also check to see that its legitimate in various looking glasses and e.g. do you see the same in ripe probes or similar? There are definitely cases where loops can/do happen beyond being transient. Router software bugs ("stuck bgp routes" / "timing race conditions on programming hardware") can/do/have happened, but are less common these days. But if its your prefix that you control, you can probably resolve it either by withdraw/re-announce of it, changing a transitive attribute that forces a refresh of it, possibly doing so via announcing either a more-specific or less-specific to backstop it.
