Yes they continue to call my cell

They continue to call my cell number I don't know who these people are.

Unknown caller. No message.

I get calls with only two rings several times a day by the time I pick up the phone all I get is a dial tone on my voip phone. I just checked my phone and they seem to have several numbers.

Received a call but did not leave a voice mail, I found on another site that in the past the number was used claiming to be  Golden West Credit Union.

"We have received several notices from our members saying they have received a text message containing the following text: notice@gwcu.org // Goldenwest Credit Union : Please Call 15084096149. If you receive a text message similar to this, do not respond to it."
