Comments regarding Nature's Control

I ordered triple threat spider mite control with 2 day shipping on Wednesday. Didn't receive it until a week later, I was out of town and night time temperature dropped below 55 degrees which kills them. I called and complained, and after a long bout finally got them to send me a replacement. Made sure I got it right when it was delivered, put in on the 2 plants infested. 2 months later both plants are dead, ravished by spider mites. Product was dead on arrival for a second time.
