Three calls yesterday, no message

Caller: Solar panels

Indian call centre (ICC)
“Hello Mr XXX
we come Inspect your solar panels.“

Me
“I’m sorry, I can’t understand you. Are you coming to inspect my solar panels?”

ICC
“Yes. Please hold the line and I get my manager.”

“Hello Mr XXX, this is the manager.
I understand you have solar panels that were not installed by a professional.”

Me
“No that is not correct”

ICC
“You don’t have solar panels?”

Me
“No I don’t”

Then they hung up.

Have received a call from this number on numerous occasions. I don't respond and just listen, and they immediately hang-up. However, I don't understand why they persist in ringing.

Keeps ringing, I don't answer
Call then back on 0431 549 966 and that won't answer the phone
Block Number suggested

we are on the Do Not Call Register too - when I answered I heard a voice that then got disconnected

rings frequently but leaves no message

Caller: Indian call centre

Damn pests. It doesn’t seem to matter that you are on the do not call register.

Sounded like an Indian accent. My husband couldn't understand what was being said, handed the phone to me and I presume a female voice asking questions scared them off. For how long is the question?

Called three time today, no message

Sick And tired off all these harassing calls to an old lady . WHY can the government not do anything about it .

Caller: Indian call centre

Why are these people trying to get in our homes and "replace" our light bulbs? LED bulbs are short lived rubbish. These people fit bulbs that flicker and breakdown very quickly. They must be in the business of selling light bulbs??!!

This number calls 4 or 5 times a day no message really annoying

Calls often. No message. Ring back and after many rings get an Indian voice asking me to call later. Blocked.

This caller did not respond when I answered, I hung up and looked up Reverse call.
