This is a cell phone number by Sprint Spectrum. These people (April) is claiming to be associated with Dynamic Recovery Company. They will tell you that you owe an $1,000 phone bill and if you pay now they will accept $600. Also try to bully you buy saying we have you on recording admitting that you owe this bill. They will continually keep trying to get you to confirm your social and sometimes they have the last four digits of your social. I have verified with Sprint that I did not owe any money and that this is a scam. You should not give out any information and report to your local police department.
