Port out time period.

I want to leave my family plan and start my own account with someone else.

I went into a T-Mobile store and was told I needed to contact customer service and ask for permission to leave the family plan, I was told it would take no more than 10-20 mins for that process. Before I left the store I asked if I could come back right away after getting permission to leave the account and set up my own account ASAP, I was told YES.

So I got with my parents and we called customer service and got my OK to port out the family plan and we asked the rep if I could go in and get it done today, I was told YES.

I then I came back to the T-Mobile store and told them my situation and they looked my number up and I was told "your number is still under the family plan so we can't do it because you aren't the primary account holder." Then I told them that the rep and the guy at that store just told me I could get it done asap after getting permission to leave. Then they told me "1 to 3 days and wait for an e-mail of an e-document for confirmation"

So my questions are, HOW LONG IS THE PORTING OUT OF A FAMILY PLAN PROCESS? I was told "ASAP", "1-3 days", "Go into the store and get it done".

Since the ported out number won’t have a phone plan anyways, would it be faster to just start a new account and get a brand new number?
