Just had missed call from same number...read above comments and advice, rang the number back and just told them to remove my number from their call register. They complied but said it may take 24 hours.. but done. Suggest everyone does this.
Thanks to all for above comments.

keeps hanging up even if I answer in 3 seconds. Frustrating.

8820 3974 can you just stop calling ffs

Same number called me 4times in 3 days. Just hang up.

Spamming

Got a similar experience of missed call on my phone. I decided to Google the number before I return call and found your comment particularly on blocking the number. Thanks for your input.

These people have called on several occasions trying to sell me on a company called "Insurance Line." I have declined on previous occasions, however I now simply hang up when they say they are from RPS. It appears that RPS is the company which does the telephone canvassing for Insurance Line

thanks to you guys I haven't called back or answered i checked on line to see who it was first thanks to your review I wont answer next time either ...

Mobile phone rang twice, I returned call only to get a Call centre. I hung up before they could finish their sales spiel.
