Apple iPhone XS (Your Choice)

so having bought this refurbished in "excelent condition" i am finding out that the on the outside it looks fine but upon opening it now that i have to replace a broken screen, number one why the charging port is faulty, that incorrect glue as been applied and that no weatherprrof seal was ever applied. Two screws are missing on the "big black bar" that holds down the connectors (top and bottome) both of those missing, the battery was original (and swollen), and there is a little tab that was supposed to be under a screw that has been replaced at and angle which shows a tell tale sign of shotty work and why half the iphone chargers in the world that are oem only work one way. I will say shotty work means lack of care irresponibility and down right trying to sell a phone for as cheap as possible... if you cannot open one up and simply replace a screen on your own i would not trust this company whatsoever and i would find another. all the problems now make sense and i am missing screws inside this iphone simply because they were too cheap to buy new ones in packs of 100 on amazon formaybe 10 bucks for 100. From now on i will be doing my own repairs this company (probably china) is terrible and take advantage of those that dont know how to or look on youtube to fix thier own.
