Called my mobile & they didn’t leave a voicemail message on it

Caller: S

Missed call, this number keeps ringing, 3rd time in 2 days and even though I mark as spam and block the number, the calls keep coming through from the exact same number ? So this scammer has found a way to bypass that on a late model Samsung phone - very annoying

Caller: " Precision connect"

Missed a call from this number, tried to call back and got:

"Thanks for calling Precision connect, we've tried to contact you on behalf of one of our charity partners.
All of our operators are currently busy, please leave a message"

Caller: Precision Connect (SHA)

Telemarketer for charity
