glstandard bank ghost calls.

Your telephone system is broken.

I get countless calls every day. But there is no one on the other side, it just hangs up. On the od occasion someone is there I talk to them. But its once every 3 weeks that there is actually someone on the other side. You call me every hour from 7 am till pm and everytime i try to answer same thing. I unbolck the number under trucaller but you change the number every day.

Every time i talk so someone they say they will escalate. But still the ghost calls continue.
