Got a call from a number on my TPS registered list, but honestly, does TPS even work? A lady rang saying she was an energy advisor, asked if I’d done any survey recently - absolutely not! What a waste of time.

I was fast asleep when this number rang, woke me straight up. I answered with a quiet hello and they just cut off the call right away? I only keep this phone switched on for emergencies, never share the number around. Recently though, I keep getting these silent calls or some random person yelling "Can you hear me?" It's really getting on my nerves having these every week. When I searched the number it came up as Core Telecom LTD, which I have no clue about at all.

Got a call way too early which jolted me awake, so I just ignored it. Supposedly it was from some company called Core Telecom, no idea who they are. Lately, I keep getting loads of these calls and they’re really starting to annoy me.

I keep getting calls from a local energy company, it’s the third one this week. Every time I block one number, they just ring from a different one. I’ve been reporting them to TPS each time but the calls won’t stop.

Got a call from some random number on my TPS registered phone, but of course no voicemail left.

Got a call from a number I didn’t know and stayed quiet. Since I’m on the TPS list, I don’t usually get random calls, and if it’s legit, they’d start talking anyway. I just let it ring out without saying anything and the other side ended the call first.

Got a call on my home phone despite being on the TPS list. A woman named Jo rang, she was asking about when the last time I had my roof checked, I guess she meant insulation but said installation. When I questioned where she got my number from, she just ended the call straight away.

Got a call from a number I didn’t recognise, and they didn’t leave any message. Probably just some dodgy scammer ringing.

Got quiet call yet again from that same place linked to the dodgy 'energy advisor' scam. This makes it the fourth one today.
