Network pass, multiple fails

Hola - 

I am interested in switching from my existing carrier to T-MOBILE. I'd like to confirm service works in my area and was informed from the sales team at T-MOBILE about a network pass. I have downloaded the app and started the work to do this. Unforunately, the app crashed during this experience and blocked the ability to start a network pass. I then went into a store for help. They helped me and the app informed me that my zipcode did not have any phone numbers available and to try again later. I re-did this step and entered another address in another zip code upon recommendation from the sales team. The app then said I had already had a Network Pass and could not get another one. I then called the technical support for Network Pass and they said they could not find any activity with my phone number nor email nor address. They also said they cannot fix this and this was the highest level of escalation possible. I need to wait 12 months or fake it with someone elses phone number. 

Who can I speak with to fix this? Where else can I escalate this problem? I'd like to confirm if T-MOBILE works for me. You are turning customers away!

Atentamente,

Cliente potencial
