Rang back got a recorded message. "Your call is very important to us, please stay on the line and be put through to the next available agent ". As I hadn't rung, deleted, reported and blocked

flagged by phone as probable fraud

Called twice in quick succession. 2nd time it went to voice mail and the caller had not hung up in time to record foreign voices in a noisy environment in the background. Assume it was a call centre of some kind. Assume it was a spam call if they opted to leave no viable voice mail. Number blocked.

Calls and either leaves no message, strange noises or just says hello and hangs up.

Missed call. Indecipherable few words on voice mail, possible Call Centre. . Have blocked caller as I hadn’t contacted this number.

Missed the call so I called back and just kept being told to stay on the line by an automated message. Wanted to see what interesting scam they had installed for me but they lost their chance. Very persistent call centre 🇮🇳💩

Never leaves a message. Just disrupts my work & hangs up. Pest!
