Tele sales call from Sumo power...5 calls in a week

Relentless phone calls, twice per day. Never leave a message, so I refuse to return any calls. This is my standard procedure for calls whose numbers are unknown to me.

You can block the number from calling if they are calling your mobile number,that's what I do and the it doesn't ring it just tells me they tried to call. In a matter of 2days I've had 7 phone calls.

I dont answer. Constantly ringing!!!!!!!! They dont leave message. Cant be important. Just annoying.

I called back number (02) 8318 3999 reached IVR for a company called Sumo Power.

Yep they keep calling me also and as I don't know the number I don't answer it. I have now blocked the number. Very persistent!!

Have received calls twice a day for the past 9 days straight. I don't answer but then call back. Their message gives option to press 2 and be deleted from their call list. I have now pressed 2 on 18 occasions. Only option is to now abuse the next call I receive

Sumo power, and won't take no for an answer! Blocked now.

They never let up...absolute pests

Sumo power. Multiple calls per day, as others have said. Added this to a contact called "Spam Number" on my phone. Never pick it up if it comes through.

These guys don't stop calling if you tell them you're not interested, they keep going. It is the worst cold-caller I have ever encountered. I hope Sumo Power goes under.

This is what happens when you fill out ONE survey online. Your details are sold to all kinds of companies. This app has saved me from the constant headache of telemarketing calls.

I get many calls from this number very annoying, don't answer yet they keep ringing.

twice a day....annoying

Constantly ring and do not leave a message

about 10 mins after they called me and I advised that I can't help them, they called again

I asked them where they got my number from...the Consumer database apparently

DO NOT CALL ME...

Several calls, asked them not to call me any more. But still the calls keep coming.

Answered the call they hung up on me. Called back and it was Sumo Power.
