they called several times, didn't leave a message. I've blocked them now

They called me to ask my 4 digit password last time and I refused.

keep call few times even on weekends. reckon is a spam call.

Caller: I don’t know

Like everyone else they keep calling and is annoying. If it’s Vodafone..well change to another company. We didn’t sign up for this.

They wanted my 4 digit Vodafone pin code. Spam!!!

They’ve called throughout the weekend also, many times a day!

This number keeps calling me and they never leave a message. So I'm thinking it's a marketing call.

Caller: Suspect Vodafone sales

Call back results in an end of message "..bye"
