My deodorant is crumbling and breaking. This is the worst deodorant ive ever used. I want a refund for what i just recently purchased(2 weeks ago) and i barely even used it!!!

I have always used mitchu spray deodorant and am extremely disappointed the last 4 cans i have brought have stopped spraying when the can the can is still a quarter full. I have lost confidence in this product as the last 4 times i have said (this one will be ok) and its not.
