Tried calling back - unable to connect "We're sorry your call cannot be completed at this time......"

number tried calling , didnt answer .. tried calling back and nothing happens

Caller: I don’t know maybe Sumo

Today I looked up plans and here comes the calls. I online registered for sumo and I looked up plans. No I didn’t answer and did not call back.

Get continuous calls from this number at least 6 times a day. Very annoying, as early as 6am through to 12am. Recommend blocking as answering it, there's no answer and redialling is an instant hang up.

Caller: Unknown

When answer nobody on other end. No return Line

Caller: Sumo Energy

I think it is Sumo Energy as I tried to check there plans

Caller: Click Energy

Put my number in online and my phone pretty much rang straight away.

Maybe CLICK ENERGY since I recently sign up and they kept ringing me with different phone number.

This number calls numerous times a day. No messages left and I can't phone back (auto hang up)
