Unable to change the PAH Line:

Your patience is so much appreciated, xxx! We totally understand that you need to view your bill on your preferred time and rest assured that we are here to make this possible for you. We tried to change your access to primary account holder however we are unable to do so since it really requires to be done over the phone. We know that it may take some of your time it so happens that we need to do this over the phone to secure your account specially that you are all new with T-Mobile. We can't compromise your security and rest assured that this will be the only time to call you about this matter. I am also going to call you back and connect you with our customer care team for further verification. Will this be the best time to call you?
