received call, do not answer calls from numbers I do not recognize. No caller ID, no message left, number is not familiar as a number of anyone I know personally or do business with. Called the number back blocking my number and IVR is Sirius XM you can select the option to be removed from the call list, I selected that then said I had to hold for a representative. Man with a heavy accent asked for the number associated with the account, I told him I don't have an account, I want my number removed from the call list then he started to ask other questions and I hung up. It is very unlikely my number will be put on the do not call list. So just blocking the number
