Unbelievable

I keep receiving spam calls from Serr Synergy Spam that only ring once on our business line, when I called back I asked if they can remove us from their calling system and the lady rudely responded with, this is the reception there's nothing i can do, you have to call the person who called you and tell them to stop calling you, even though I called the exact same number back, and that there is no system in place and they get it off google and she asked me to remove ourselves from google, I asked how do I remove an existing business off google and she confidently responds with I dont know. I ask to speak to her manager or get managers details and she tells me she cannot give the details to me and that the manager is not in. This is just pathetic
