TOQI Technology Ltd. review: Wax cartridges

I ordered the black ones and they sent me the white ones which are not the same and they just don’t work and I believe the lady thinks I’m not being truthful now they want me to pay shipping to send items back when they didn't have correct items in first place .these items are for THC to be used with and you can't mail used items like that back once you load them this lady is treating me really bad it's unbelievable
