Who called from 9712597771

Got a call, picked up, noone there.

I had looked at the green coffee site too after i saw an ad for it on a newspage.  Got the call but didn't answer it and when I called back, busy. I also got a text from them offering me a discount to complete my order....

Lady called asked for me and hung up, I called back and it rang twice and then rang busy.

Now they are texting my phone this is a Green Coffee telemarketing call. How do I get rid of them.

I got 2 calls from this number also, it is very annoying, I think it must be a telemarketer
