I called back the number 0480 027 259 and reached vm that did not mention the company name

Span span span ....so sick of overseas call centres trying any combination of numbers to see if a valid mobile then they onsell the details to telemarketer to then harass ya on top. Block the b@$tard$ .

No answer

Called back was an automated woman regarding an echo test, spam

Spam do not answer

when I received the phone call, no one responded and hang up. I found it is rude and may be scamming to get someone's private information. Do not take this phone call.

I also received a call from them and did not response.

picked up the call, no answer from the other side

I also received a call from them but didn't respond.
