I had been told that the company was going to overnight me a new sensor and transmitter. I did not have any test strips as I count on the CGM to let me know how my blood sugar is. they were going to overnight it to me. they were also going to send me a package so I could return the old transmitter and sensor. Since they had told me that on Friday night, I didn't expect to receive anything until Tues. When Tues. I came I received a package from them. Since I was out of test strips, that was good news to me. When I opened the package I found things to return the old transmitter and sensor but no new transmitter and sensor. I called them and explained the situation. They said they hadn't put in an order for a new transmitter or sensor. So, they had made a mistake - though they never admitted it. I had to borrow money from a friend to buy some new test strips. I don't trust them to actually send me things they say they will send me.If there is another CGM company, use it!
