I've asked this on alt.cellular.t-mobile, but allow me to tap the T-Mobile expertise here as well, please.
Back on Dec. 29 my Nokia 6610 handset spit out the "File format unknown" error when trying to access t-zones. The tech CC rep who wrote up a ticket on that issue never did get back to me with any status, as he'd promised.
But this evening about 90 minutes ago t-zones was working again, seemingly, offering access to, among other things, My Account, and from there also Bill Summary, Current Activity, Plan and Services, etc.
Trouble is, the My Account data is for someone else's T-Mobile account, not mine! What's more, it changes from one access to the next. First, it showed1181 minutes remaining, with New Minute Start of 01-11-11; the next time it showed 1013 minutes remaining, with New Minute Start of 01-20-11. The Plan and Services descriptions also had nothing to do either with each other or with my actual T-Mo plan.
A call to T-Mo CC to resolve *that* question resulted in an agent finally coming on line after I'd been on hold for 58.5 minutes; after getting "the picture," said agent in turn put me on hold while consulting someone/something and, 10 minutes later, my music on hold went dead -- no, the PBX hadn't quite dropped the connection to a fresh dial tone -- and 10 minutes after that I gave up on the possibility that my call was still in a live T-Mo queue and just hung up.
Known T-Mo New Year's issue? other? advice?
TIA; and cheers, -- tlvp
