It's good that you recognised the number. They may try to call again from another number. Block their xxx
I've got to the point whereby if I don't recognise the number and the name display doesn't show a name, I don't answer it. If it's important, they'll leave a message. Otherwise, block their xxx!
They say they’re from diabetes & ask if I have any items for donations. I have donated in the past & if I had items for donations I would most likely have said yes, but I just donated to them so I said “not at this time”. That was 4 days ago & since then they’ve called called me every single day, so I’ve blocked them. I’ll drop off to a donation centre rather than getting spammed with all these phone calls.
I have been through this before. If you say yes to the pickup, they will call about every 6 weeks. Requested name be removed with no action. If you block number they will call from another.
