I only have used their service 2 times. The first time I got a replacement device it wasn't working right after 2-3 months. Then, I tried getting a replacement for that phone and they send me a phone with a broken fingerprint sensor and the phone wasn't even compatible with my service. I found out by going to my local boost store and they said that the model I had wasn't compatible. SO I CALLED AGAIN! I told them that I was told the phone I had wasn't compatible and they said ok we will exchange it for a new one. I said will it be a different phone, they said no it will be the same but it will be compatible. I said can I get a different phone. And they said no we will send you thing one. So I said ok. I am ok with it if it works. So a couple days goes by and I get the new one. They phone wasn't compatible again! Only this time the sensor in the back words but whats the point if I can't connect to my service. They are one of the worst companies that I have ever dealt with. They really pissed me off and I am done with paying their monthly fees and will be switching carriers. Plus the phones they send you are refurbished. That is asking for a problem to occur. I can call them back to see if they could replace it for me but I would rather pay for a brand new phone with T-mobile any day. Go to hell bright star. More like death star!
