CPNI violation

No one has helped me with this
I had to file an FCC complaint due to T-Mobiles lack of response.

Customer care representatives do not follow up on scheduled call backs. I’ve been promised countless call backs from representatives and they never follow through. I don’t know how else to escalate this issue. I’ve submitted an FCC complaint due to my account being accessed by store employees without my consent.  I’ve called customer care to complain and they haven’t done anything about it. Lines are being activated without my consent and nothing is being done. I’m going to end up suing T-Mobile due to violating my contract and multiple CPNI laws.
I’ve called more than 20 times and I’m always promised a call back or placed on hold and I have to explain my story all over. I don’t trust T-Mobile.
