Free phone just pay tax

Went into Sam's club June of 2022 so not long ago guy totally freaking lied to me told me I can get a free phone and just pay $8.176 for the tax  And then $8.99 a month for all state insurance   Huge effing lie   You have to turn in your old phone which he told me that but still told me this was free I asked like 5 times are you sure it's free yes when you turn your phone in all you have to pay is a tax on this phone so I got a Samsung Galaxy S22 well I get my bill and I'm getting credits off of the phone of $22 a month by getting charged $29 a month for the new phone for 36 months that is not free that is about $350 for the phone and then the 81 tax plus their bill is higher total freaking liar And it took forever to get the phone to get the credit such a lie I was with T-Mobile prior $55 a month I mean  what a lier ... Don't do business with Sam's club in AT&T because they lie they lie why would they need to lie all she had to say is the phone's gonna be approximately 300 plus dollars words plus tax lied his a** off
