Had received 4 calls on Friday,and 3 calls today the 10th of September 2016.This person said he was from the IRS.I told him if the IRS was trying to contact me that they would by mail.Not by a phone call.He also said that they were going to sue me.The number is from Alabama.I have told him numerous times to stop calling.This person is an Indian person.He is very rude on the phone.It is just taking up alot of my time with these people calling constantly.something needs to be done with this.Thank you for your time.I hope this gets solved.I have contacted my phone provider and they wanted me to contact FTC.I have been on the do not call list since 2005,and they are still calling.
