RC application sent - how long until biometrics

[PeatD]

I'm in a similar position and am getting worried. Applied as the non married partner of my Italian boyfriend. Sent Feb 11th, payment taken Feb 26th. But nothing since, no reference number or letter. I called HO 2 weeks ago and they said I would receive some kind of confirmation within 4 weeks of payment being taken, but I've still had nothing. Starting to worry as I need to request my passport back for travels in July and because my Australian drivers licence is about to expire (so I need to send it back to Australia for a replacement); don't want to be without ID.

I'm reading fairly mixed experiences on this forum? Can anyone please advise if theres anything I can do? Thank you!
