Not a secret that our days identity fraud is on the wild loose ,how many people you know that been victim ether with huge fraud or small credit card charge that was not authorized. This might be owner fault in some cases for example forgetting card at gas station or any place else .But also might be one of the list of company you use such as any utility company cell phones company or more . Lets talk about one of them and i will give you true example ,that happened to me. As we all know great advertisement will work in company favor and my case was one of it . With decision o save some extra money i switch to T-mobile USA after comparing couple of biggest carriers in US . Everything was great at first and one day i received a call from unknown number , we had an unpleasant conversation but i had a chance to ask how come he was able to get my number and answer i got shocked me i been told i that they in possession not only of all my numbers on the account but my address as well and information was provided by one of tmobile reps.i am not hiding from anybody never even seen that person before .At this point i called tmobile and had no response from them so decided to call Federal Communication Commission. That made tmobile response way faster , they called me said that they will look up person who provided my personal information that was first and last time i heard from them . Company would not respond to any of my calls voicemails email . This situation made me do my own investigation it took me 3 day to find who and why also to who my information was provided .Called tmobile again but no response. I dont really worry about person who called me or annoying calls , i am worried that anybody can go to tmobile store give couple hundreds to rep and get you info phone numbers address not a big deal but i remember myself giving them my ssn my credit card copy of id , in my eyes this is important information. Think about this before you will go to tmobile .
