@tmTmobilehelp_x do not allow this person to call you and download the Lemfi App. They tried to get me to sign up to get a refund from T-Mobile. @TMobile won't use 3rd party apps to issue refunds.
@TMobile lied to me about cancelling my last line and decided to go ahead and charge me for another month after porting 5 other numbers to ATT. Former 24 Year customer.
