I returned all the medical supplies sent to me in the amount of time specifide because the sensor was faulty and not accurate. I called and complained nurmous times to never have my calls returned, so I returned their products in full. They took money off my husbands credit card for over {$300.00} that needs to be returned to me. They have been harassing me non stop and I 've explained to them that I will not pay for something they already have back. I sent certified I have signed receipt! Thank you
