Metro by T-Mobile review: My upgraded phone

To whom it may concern,I went into Metro by T mobile on 11/24/2023 at 5;12 pm to purchase an upgraded phone. I purchased a Wiko Voix 32 G for $74.89. Ever since i got this upgraded phone it has been nothing but trouble for me. Apparently everyone i talk to on the phone cant hear me. I can hear them talking to me but they cant hear me. I have contacted Metro by T mobile on numerous occassions about other issues ive been having with the upgraded phone. Nothing ever got resolved bc the person at that location said there was nothing wrong with the phone. I even went as far as to ask if they could switch my upgraded phone back to my old phone. They said yes but it would be a $25 fee to-do that. I cant or wont pay that bc i feel like its not right for me to still keep putting out money for a phone that isnt working properly. I feel that i should get a full refund of my money i paid for this upgraded phone that doesnt work like its supposed to. With that being said if the problem doesnt get resolved in a timely matter i may just have to seek legal action. I work hard for my money as im sure you do to. If the shoe was on the other foot youd want your stuff right as well. Id greatly appreciate if you could get back to me on this situation.
