I truly want to help get this straightened out because it sounds like you had a ton of data saved up and now it's gone. Did you switch to the T-Mobile ONE plan while on the phone with them? If so, moving to the T-Mobile ONE plan is likely why this happened because you have unlimited data therefore no use for a data stash. This definitely should've been presented to you prior to switching your plan and our T-Force team (Facebook/Twitter) can review your account to see if you're able to switch back.
Was anyone able to get your data stash amount back if you didn't switch over to the T-Mobile ONE plan?
I do want to call out that you have excellent feedback regarding what you should be able to view/have access to on your My T-Mobile account. The ability to view your data stash should be easily available.
I absolutely did NOT switch ANYTHING, and a person told me that my data
stash expires in 12 mos. Not the accrued data itself but the data stash
part/service of my plan. Which is bs i told her I've had it over 2 years,
and never had to "re-add" it to my plan. That's just sounds ridiculous.
And even this was after 3-4 people tried to convince me that my daughter
and i BOTH conveniently ran thru ALL of our data AND data stash!
I am HIGHLY upset about this. I paid for that data and plan! And it just
vanishes with NO WARNING? That is THEFT.
