Problem with Insurance coverage replacement

I'm going through this now with mechanical issues that are suppose to be covered. They're pointing the finger at each other. I went to the store 3 times, talked to about 15 tmo reps and 3 Assurant reps. Me and the rep at the tmo store even called tmo support. This is the second unlocked phone that i've purchased through Samsung that they refuse to cover. They claim its still in warranty so Samsung should lift the weight. My phone's warranty expired on the 26th. Data issues have been reoccurring with no resolution on tmo part. One TMO rep even tried blaming it on my phone lol. Welp start filing bbb reports, i think i'll get legal assistance with this issue. My 360 protection byob clearly states that it's extended out of warranty coverage for mechanical, theft/loss and cracked screens. Asurion was no hassles but Assurant and Tmo yeah naww. Such a rip. I'll be filing with the AG also. Pure buxxxx from both of them this is why i stopped purchasing their phonesa d go straight to Samsung.
