I have a problem with my lung muscles not allowing my lungs to expand enough to get enough oxygen when I am walking or doing anything around my house. I was ordered by my pulmonologist from *** ********* to use this ***** machine to give my lung muscles a break and hopefully allow me to get better. I bought the machine on 2-20-2020 a Thursday, and I paid for shipping to arrive on Saturday 2-22-2020 I paid about 63 dollars extra to have this machine so I can breathe. I was told ***** would deliver the machine, and Saturday night came and went with no delivery. I contacted the company again on Tuesday thinking I would have gotten it on monday2-24-2020 surely some mistake had been made. We were told the product would be sent overnight and we were refunded the shipping amount of 63. I am here on 2-26-2020 and nothing has arrived and I check *** ** which says nothing has been scanned yet. I cant get this machine anywhere without a prescription, I gave these people the prescription, and ordered it, and yet there has been no delivery of my medical device, which I need to help me breathe. literally I lay down not being able to breathe, and im wondering where is my machine? How can you tell me you are shipping the product over night and it doesn't arrive, and then tell me again you are shipping it overnight, and AGAIN IT DOESNT ARRIVE? PLEASE SEND ME MY ***** MACHINE AS SOON AS POSSIBLE.
