** Updated & Resolved **
Finally got this resolved this morning. After an unsatisfactory resolution from 'Brian', a CS Supervisor, I sent a verbose letter to
Dan@sprint.com. I also CC'd ecare, and
executive.offices@sprint.com. Additionally I filed a complaint with the Better Business Bureau. (I think that was the kicker.)
A few days after sending the letter and complaint, I received a call from Jeffrey H. at Dan Hesse's office. He handed me off to 'Claudia' at Sprint Executive and Regulatory Services. After a couple conversations with Claudia, I received a voicemail this morning that she had been able to restore the unlimited text messaging option that had been removed. I was rather shocked, pleasantly so. After listening to her v-mail, I immediately logged on to confirm, and there it was. An hour later I got a 2nd call, which I answered, Claudia again calling to confirm I'd received her message. "And would it be alright if I responded to the BBB that this issue has been resolved to your satisfaction?"
I later got an e-mail from feedback and replied affirmatively. Claudia stated she'll also be following up with me next week regarding the pending rebate on my recent TP2 purchase.
So overall I came out ahead. I still have the $165.00 credit on my account that Brian applied for his 'band-aid' fix and finally the missing option restored. (Something more than a dozen reps previously insisted couldn't be restored...)
While I got the resolution I was looking for, I am a bit disheartened by the amount of frustration and effort involved.
Prior to this problem, I'd not had reason to call CS or Tech for over 2 years; closer to 3, when I got my Mogul.
So, if they screw something up and don't / won't fix it, stay on them. Keep cool, but be persistant.
Thanks for your comments. If anyone's having issues and wants to see my letter, I'll be happy to paste it. (as I mentioned, quite verbose. lol)
