T-Mobile Data Breach

I was part of the data breach. I received a text message from T-Mobile that I was affected soon after the news broke about the breach. My friend received his a few days later. My account on the app has a box at the top that indicates I was part of the data breach and what I can do about it. I was able to finally sign up for the McAfee protection. It took awhile, at first I couldn't create an account and then I had to wait for their email which took several days but it paid off. I found out some woman in North Carolina has my social security number (this was at the beginning of this year, prior to the breach). I just signed up for LifeLock through Norton 360 also. I have been in the process of locking my down social security information with extra protection, two factor IDing my bank logins, freezing my credit, checking credit reports, etc. I had my cell account changed so my number can't be ported out to another carrier. Yesterday I received a call from someone claiming to be from T-Mobile. It even popped up "T-mobile" on the display. I thought it was something about the breach so I answered. He said they were just checking in on their customers. I got suspicious right away because they have never done that for me before. He had all my information but got the phone plan price wrong so I got even more suspicious. I would not confirm any of the information he had, just kept saying "hmmm" because I was mad at T-mobile and was not able to verbally unload on him due to being at work. Knowing I was at work, he still wanted me to stay on the line while he "checked the cell towers in my area". I panicked and hung up. I highly doubt the call was legit. I have now set my phone to not allow any calls through that aren't on my contact list and they go straight to voicemail. T-Mobile is a huge company. They had enough money to purchase Sprint but they couldn't make sure my personal information was protected better? I am livid and every time something like the phone call from yesterday happens I am even more furious all over again. I have done my research on other phone plans, I can't beat their price for the phone plan I have and a data breach can happen to anyone but I am the one who is ultimately paying the price for their mistake. How much is enough? Because I am just about there. I'm sorry this is so long but I wanted to let you all know how I was contacted by T-Mobile, that I was eventually able to get into McAfee and that scams/scammers are happening because of the data breach. Stay safe out there!
