T-mobile stole my social security number

I recently had an issue with my phone and called later in the evening to remedy the problem. Because it was in the evening an out of country T-mobile representative tried to fix the problem but was unsuccessful so she transferred me to technical services. The technician that took my call was also out of country asked for my full social security which I reluctantly gave it out to resolve my phones issues. Approximately 3 days later I got an alert from one of the credit reporting agencies that my social security number was found on the dark web. Coincidence, I DON'T THINK SO! I never fall for scams and I never give my social security number unless I absolutely have to. I talk to a manager during the day who was state side and he stated that T-mobile has to occasionally ask for the social security number to ensure they are talking to the right person. Why do we have a PIN number than??? He stated that the fraud department already looked into the problem and found no evidence that my social security was compromised. I asked if the phone call was recorded and did they question the individual I spoke with.  He stated that he doesn't have access to that information but if I wanted to write a letter the the fraud department(really, a letter and not an email) that I might be able to get more information. Judging from what others have said when they wrote the the fraud department and got NO correspondence, I'm not going the waste my time. I than asked the manager to have T-mobile pay for one year of fraud protection and he said T-mobile doesn't provide that service and will not pay for a third company to monitor my account. What did I have to do to protect my entire financial standing? I had to call all three credit report companies and put a fraud alert on my account, call the social security and put a freeze on my social security number which I'll have to go to the social security office and stand in line for god knows how long if I ever want to unfreeze my social and finally I called the attorney general to report the issue. Talk about a huge hassle and scare for me!!! Why the H*LL does T-mobile every have to ask their customers' for their social security number??? Than to make matters worse, THEY DON'T OWN UP TO A PROBLEM THAT THEY CAUSED!!! I've been with T-mobile for over 25 years and this is how they repay my patronage? I'm now in the process of looking for a new cell phone company because I can no longer trust T-mobile. Sad, isn't it, that T-mobile stole my social security and don't owe up to it or help it's customers who suffer because of their negligence. Than, the only way to communicate the the fraud department is through snail mail. DISCUSTING!!!
