PAC porting issue

My old number was supposed to port across yesterday. I am not able to take inbound calls.
Customer service has been useless, either saying just to wait or giving me instructions that don’t make sense (turn my phone off for 4 minutes????) I’ve tried emailing the CEO and Ops director but also nothing back from them.
Anyone had experience with this and now howI can fix? At my wits end, had this number for years and losing it will take me ages to sort out.

I've had the same problem it's been three days since my number was due to be ported. It shows up as being ported on the Lebara end but not on my SIM card.
Called customer services twice and they said it was sorted or would work in half an hour but it still hasn't

Me too. I am leaving Lebara after 3 days.
