Changed too quick?

Pre-payment smart meter for elestric and gas)
I went from British Gas to EDF (electric and gas) and now going to British Gas

19/04/25 - applied to switch to EDF to start 25/04/25 - to go in to credit mode and pay by Direct Debit.
19/04/25 - email from British Gas confirming I am leaving
22/04/25 - missed call from British Gas retentions
24/04/25 - missed call from British Gas retentions
25/04/25 - EDF have taken over supply, both meters changed to credit mode, prepayment balance no longer showing (I hope to get a refund from British Gas) - readings given myself.
25/04/25 - spoke to British Gas retentions, offered me better deal (al least I hope it was) and they going to supply from the 30/04/25

I have not had an email from EDF confirming I am leaving, I am within 14 day period to cancel exit fee free (I hope).

Bit worried as nothing from EDF to confirm, should I do what I did above and just for British Gas take over, supply readings and do nothing with EDF?   Only asking as I do the same with Broadband annually expect this time 2 months ago it was not automatic do nothing.
