T-Mobile's BOGO deal on the LG G6 was supposed to last until June 8. However, surprisingly, it has been pulled. The link to the deal web-page on the magenta carrier's website is now inactive, and the following leaked screenshot clearly confirms that promotion is over. No information on why the deal has been pulled abruptly. As you can see in the leaked image above, T-Mobile is asking its executives to refer customers inquiring about the deal to LG. And indeed, that's what is happening (see image below). Via
