When I called back it comes up as "Call Failed" straight away.
I have several of these calls all with the same area code (02) but the numbers are different.
Scammers or telemarketers???
Looks like I will have to block this one too.

Caller: Scam

Do not answer. Scammers from India using a fraudulent number

I also called back this number and it is a dead line

I keep getting the same thing.
As the number calls, I block it.
All the numbers are the same people, 02722938xx.
Any of the ‘xx’ are the same grip of numbers.
Some dodgy schemers trying to tell you how to make $$’s.... why, if it’s so great, are they working at an Indian call centre?
Then it’s the ol’ we have great software for your hone pc... not a smart idea to run on ones hime system, if you do, chances are they will suck all the relevant private data off the hard drive. Lookout !!

I think it was a telemarketer?

I called back the number (02) 7229 3861 but the call didn't go through
