Who called from 7062180214

I received multiple texts today from 706-218-0214, the person sending multiple texts and then being rude when I asked them to stop texting me.  They said they were part of a group text but my sister did not send anything to them, strangely they knew her name but this number is not on their list.  Some one is playing games somewhere.

Forward the text to 7726. It will be investigated and blocked by your cell provider.

asking me about my interest rate on my credit card
