Auto-dialled call, took a few seconds to get connected to a call center agent who said they were from O2 and were pushing a new SIM deal. I hung up then.

Unsure why I got this call but the line was bad and I could faintly hear a man on the other end. The caller ended the call not sure if it was a genuine call for me
