AHHHHHHHHHHHHHH i hate petco!!!!!

of course i didnt do my research before i got my bp, so i went ahead and baught it a petco.... the next day i pull him out 2 handle him and i saw and INFESTATION of mites!!! omg.... i went back to petco with the snake, they told me that a little of this mite spray would work. So i cleaned his habitat every night... i did everything they told me 2... of course a month and a half later im still stuck with mites.... i brought him in to petco this after noon.... the women told me that she could not do anything with the snake because the snake wasnt under there warranty anymore... then i told her off.... i told her that this was there problem in the first place and that i have been paying money out of my wallet to fix it. I yelled at her told her that she needed to do somthing about it and that she is not doing her job of pleasing her consumer and all this stuff... uhh omg i just went off on her and now i feel kinda bad for yelling but thats what petco gets for selling sick animals
