Happy Friday, madhushastri!
I did a bit of digging with the Switch2T-Mobile offers that we currently have going on which include Carrier Freedom and #GetOutoftheRed. I totally agree that you should've been informed that you were not eligible prior to porting back over to T-Mobile and I'm truly sorry that we didn't do so. Per the eligibility requirements for the two offers I previously mentioned, you can only take advantage of them one time per phone number, per offer.
Hey there. Did you still need help with this? We really wanna make sure we've done everything we can to get you this offer. Please feel free to message us back so we can continue to help.
