Bad service

I bought a Samsung A05 from Samsung Cresta, the unit was giving me problems with the speaker I would not hear the voice when receiving calls. Then I got assisted by Kyle that works in the store the most useless customer consult, why I call him useless He first says apps on my phone especially true caller is the one causing the problem Then he asks what cellphone network provider using, I advise it's cellc. He says u must change that service provider cellc has bad network. I ask where I'd the stores technician he lies and says his not here his gone out. After a fee minutes the technician approaches me I ask where do u come from cause Kyle said u not at work. He was confused and said his not sure why Kyle said his not at work. Kyle continues playing with his phone checking his tattoos his service is pathetic. I'm grateful to Washington because as frustrated as I was he managed to explain the stores process in a kind manner
