There is a pretty good chance the reason you haven’t had order confirmation is because you are ordering something very difficult to provide , a landline that isn’t using broadband ( that you pay for ) to host the service …..
Since the PSTN switch stop sell ( the exchange equipment that used to handle phone calls ) telephony in effect now needs broadband to work , in most cases the customer wants broadband as the primary product so adding telephony is straightforward, but you want telephony without broadband , so that causes issues , new IP telephony ( IP , internet protocol ) , needs broadband to work .
There are two ways BT are considering providing telephone without broadband, in this new era , now that the PSTN system is unavailable to new customers , it’s still working for telephone only that were already on it , the two options are ,
1….BT provide you with broadband for free , you don’t necessarily realise you have broadband, you are given a mains powered box that plugs into the phone line , you also plug your phone into this box , you are using IP telephony via broadband even if you don’t know it , but are only charged for the telephony ( but TBH , a standalone telephone service and a basic broadband /telephone combination are not much different in price so I don’t know why you didn’t take broadband , unless you are on a social tariff )
2…BT connect you to broadband but it’s via an ATA ( analogue telephone adapter ) in the exchange building not at your home , your phone works like a PSTN phone , but behind the scenes it’s IP telephony.
BT haven’t said the way they are going to do this , there are trials for the ATA setup , but no date for rollout ( not that I’ve seen ) and no one has posted here about getting a type of free broadband to run the telephone service , TBH , if there are some customers like this , getting free broadband to run the phone service, they may not realise the mains powered box is a type of broadband router , but no one has confirmed this type of service either .
I suspect your order was taken , it’s failed , and they are now contemplating what to do with someone like you that wants a telephone service without an associated broadband service , ( you must be in a tiny group of new customers that don’t want broadband and just the phone ) , any other provider would have just told you to go away , that you can’t have just a phone without broadband , unfortunately BT can’t do that so have to take your order and then figure it out
