Making an assumption that your ‘fibre’ is FTTC, its unclear why the BTw site doesn’t show any open orders , there must be the one that generated the ‘ sorry to see you go ‘ from TT, and presumably at least two orders should exist , a stop or stop renumber ( TT) and a start or start renumber (BT) ( depending on if the phone number you have currently is being kept )
It’s not necessarily the case that ‘BT’ could tell you much about orders for the other company’s involved , I would think that although it’s a common ordering system, it’s unlikely that an individual company can snoop on another company’s orders...but they could ( presumably) tell you if the BT order is still on track, but there is no reason to suspect it isn’t.
As already stated, the chances are the only potential issue is if Eclipse haven’t either been notified or have not acknowledged your ‘cease’ of their services , and they continue to bill you even after the physical disconnection ,or they insist on more notice than the landline , calling them to check I would suggest is low risk , but if risk adverse , wait until BT are suppling service then call .
My suspicion is that you probably should have received something as the ‘system’ you would think, takes into account a situation where a SMPF customer may change the broadband provider but keep the landline provider, if the aim is to stop all slamming , then Eclipse would presumably want the opportunity to stop the change over, by you responding to their ‘sorry to see you go’ communication, but that may make you think by calling them , it gives them a reason to get involved, and maybe mess up the migration.
