metropcs lied to me to make the sale winter haven Florida

i went to get my phone warranty but was told it was pasted the year, but i dont think so. so i was forced to buy a new phone. i dont think it was passed a year. so i got new phone. after looking at the receipt i was charged screen protector but the only one i got was what came with the phone, still charged. the guy at the store lied to be about the phones OS and and internal memory. he lied to be to make " a sale " so im stuck with phone i dont want/need and out of money because was charged things i shouldnt have been charged. people like this makes me want to go somewhere else who is honest. what are my options about this situation?
