False advertising at its best!!Sprint was running a promotion through Best Buy. The promotion centered around the Samsung S7 and S7 Edge. The promotion included a free upgrade, Samsung Gear VR, $400 gift card per upgrade and 50% off the cost of each phone.On 12/20/2016 @ 1811 hours, I upgraded my daughter's phone and mine to the S7 edge. I received two $400 gift cards, two Samsung Gear VR's and was told the 50% off the cost of the phone's would show on my bill in 2-3 months. I'm currently in possession of the recipt showing the promotion savings and have presented it to the Best Buy representative.Needless to say, I have yet to receive the 50% off. I've brought the issue to a Best Buy representative in February 2017 and was asked to let them reach out to their Sprint representative to resolve the issue. I've reached out to Sprint to be informed that was a Best Buy issue not ours. Here we are in April 2017 being told from Best Buy, it's nothing we can do about it because of the time that has elapsed.The only reason I upgraded our phones wss due to the promotion being ran.Bottom line up front. It does not matter if the promotion was ran by Sprint directly or through Best Buy. The promotion must be honored and not placed on the customers shoulder to defend.
