Employees or Agents of this company calls you and identify themselves as an employee of your local phone company and advise you that you are required to make a decision regarding your outbound long distance service. The person calling does sound legit but I did notice they called from a blocked number.
Part of the scam to make it look more official and they transfer to another employee/agent who represents themselves to be with a company that verifies that you do indeed want to switch to LDCB. You are instructed to answer yes to all questions to speed through the 'approval' process. The last question asks if you are ok to be charged 15 cents a minute for all outbound calls in the US an Canada.
I recommend you say NO!
