Can't place or receive phone calls.

you have to give us more info for us to understand your specific case.
On a side note, I had a similar issue yesterday but my phone was working fine for 6 months prior to that.

works for me, contact them directly try the chat bubble

MTL here, I momentarily was disconnected today it showed ''no service'' but it was seconds only

I have had zero interruptions since the outages in April.
