Missing O2 Sim

Just moved over from Virgin Media Business to VM Personal Volt package.

Arrived ok and swapped over the routers and alls well.

Except...where is my O2 Sim ?!, repeated phone calls left me tearing my hair out, transfered back n forth between VM and O2 with no success.

Virgin say SIM should be sent separately by O2, O2 have no record of this. I bought my Volt pacakage from VM, any problems should be upto them to sort out, they want me to deal with O2, order a Sim, pay extra costs, etc !

How can a simple issue cause so much hassle ! I was about to leave a rare good review of the process so far but now Im back to agreeing with all the 1 Star reviews on TrustPilot !
