Cant make calls

[AUTISTICDJ01]

Hi I can't seem to make calls it says it's calling but not ring then ends the call...... signal and data fine just calling is an issue ...... has any1 else got this issue.... I've tried clearing cache and updating my phone turning airplane on and off resetting the network providers part change to force stop calls to get it to refresh and restarted my phone...... what else can I do...... I've checked 3 to see if any shortage or an issue with cover but says no reported issues xxxx

Same can’t make or receive any call since 13.00pm today. The amount of business calls I have missed is unbelievably upsetting.
