port out scam

my phone number was ported from my phone and was used to gain access to our bank accounts, 

 I realized what happened right away and called Cricket, but they were of NO HELP.   When i question the agent at the store , he said that the number got ported yesterday at the Cricket store .

When i question the same to Cricket customer care over the call, They say that the number was ported in the store yesterday but they have no no way of tracking what store it happened and which agent authorized it . This is UTTER BULL . Im guessing its Inside Job and some one working at the cricket store did it . 

Customer care Kept asking me if I am sure that I ( or my  mother or wife on the same plan) didn't port the number or maybe it was someone else we knew. What the heck is that supposed to solve? No one at Cricket seems to know or care how to protect our accounts! 

Again, I have read multiple reports of this happening to other cricket customers.

I will be reporting this to the Better Business Bureau and FTC .

Cricket is the worst at protecting its customers and even more so at helping them! How is it that easy for a stranger to pull a scam and steal a phone number while being impossible to prove that you, the account holder, DIDN'T AUTHORIZE IT!!

Cricket has the responsibility and the obligation to investigate and do everything they can to help protect their customers who PAY them for their service!!

Phone calls to Customer Service went nowhere
