I had 3 calls from them yesterday and another 2 today at my work. I wasn't answering them as I knew they were spam from having already been called from them on Monday. I answered the last call with just a 'Hello' and a guy finally was on the other end trying to see web marketing services. I told him we have another company that handles this for us and that I want us taken off the list. He told me he'd do that and asked if the company we used was local which I told him yes. Then he tried to tell me that all our stuff was going to them and I processed to tell him it was impossible as I know he's just trying to get me to sign up with them. I told him one last final time to take us off his list while he was talking and I hung up on him!
I get several regular calls from different companies in a day. Similarly, one day I got a call from 289 275 0520; they introduced them as Zoom Web Media. I ignored it, mingling with some other commons. However, after getting repetitive calls from it after some intervals, I pay heed to it. Now I have been taking professional SMO service for six months from zoom guys and they are doing good.
