That was one of the first things I did when I found out my stbxh was abusing my phone number....I got a new phone number & blocked his number completely from my phone....& he will NEVER know my new number to give it out again as a reference for his credit though maybe I wish he would because I would tell them exactly how bad he is with his finances & all the bad things he's done financially & they would NEVER give him a loan....but I want my peace totally cut off from him as much as possible until I get the divorce finalized.
