$650 Switcher is very Misleading by Rep

I went to AT&T Cor Store ask about coming to AT&T because I heard AT&T pay up to $650 to Switch now the Store told me we would give you $237 for your iPhone and and whatever you old Verizon or n final bill we would send whatever you Verizon on Visa Card lookin looking how long it take I see many complaints that's misleading and there is no benefit to switching think every customer should get what is told to them if this wasn't I would have stead with Verizon. The issues is AT&T is messing with people financial stability which causing customer to come out extra Money I either want what was told to me or or my device back I can go back to Verizon this have so irate and frustrated this isn't right how store and reps get away with this and customer have to suffer and when you call you are pass around like a ball listen to that automatic system and rep try to do what they can and they even get transfer around this have to stop period
