Indian scammer from multiple numbers with (02) 8527 prefix. Went to voicemail and caller didn't realise. Kept saying hello hello providing Indian accent and could also hear other callers in back ground.

SO many calls from these 8527 numbers! There's been about 11 or 12 calls just in the last 10 days. They just won't give up. I don't know who they are, but they won't leave a message so I refuse to pick up. I'd love to block them but it's a slightly different number nearly every time.
