How to be a " Customer* " 101:
Print a copy of the post above mine, highlighting the part where it is stated that the rep went in the back and got a new vibrant, and just copied the sdcard over. Go in and request the rep in the store do the same. If they don't, make it glaringly obvious that you are writing down their name, ask for their manager's name, and then got on the phone with Tmobile Customer Care while standing in the store in front of the rep. Ask the phone rep to intervene and explain that you are only looking for a simple customer service request, that involves no loss on T-mobile's part of materials or resources other than taking the time to resolve your problem. If the the phone rep is also non-cooperative, ask to speak with their supervisor, and tell them you will be filing a complaint with the Better Business Bureau that you will not be renewing your contract with them, and further want them to cancel all extra features and reduce the contract down to the minimum level of service is with the most simplified, least expensive plan. Then ask for their corporate mailing address, and ask to be escalated to their boss.
To be honest, I would be very surprised if you managed to get even halfway through what I just typed before they take care of it. If you do get all the way through it, go to a different store and repeat the process. lol
*If you have ever worked retail, you will understand the many alternate definitions of this word, which I will not go into but which could be summarized as being on the intellectual level of and/or related to /b/.
