I just wanted to vent and see if anyone has any advise for me... We have been experiencing dexcom issues off and on for a few months. I had to go through a whole box of sensors while being told that it is a sensor issue. I got ONE replaced and had about four conversations. I finally got ONE good sensor and thought all was well (this was once I tried a new box). I figured that the next sensor would be fine and all this craziness (sensor error 1, ???'s, sensor error 0) was behind us. That was not the case. Tried the new sensor from the new box (second one that I have used out of that box) and here we go again!!!! SENSOR ERROR 1 and now SENSOR ERROR 0 (what does that mean, by the way). So, he has had this on for over twenty four hours with about 5 hours of readings that were inaccurate and mostly sensor error 1, along with ???'s and now sensor error 0. I have to call them because two times ago, when I had issues, I was equally as patient (trying this no good sensor for two days until finally pulling it) and was chastised for pulling it without having had a conversation with dexcom first. The time after that I had a conversation and they told me that they would call me on Monday (since my conversation was on a weekend) and they never called, no message from them either SO I didn't get THAT sensor replaced, of course. Now, I don't want to call on the weekend, because it ultimately does no good but I need to pull off this sensor and AGAIN try another one! What is the deal??? This cannot possibly be sensor after sensor after sensor, even from different boxes with different expiration dates! They wouldn't even entertain giving me a new transmitter b/c sensor error 1 and ???'s are apparently always (even though I cannot believe this) caused by sensor issues. They replaced my receiver because it clearly had an issue, my warranty is getting ready to expire so I guess they don't want me to have a whole new setup before the warranty expires. What would you do? I am so tired of spending time on the phone with dexcom. We have other things to do! Any advise is appreciated! I have had 6 sensors from two different boxes NOT WORK! This is really unbelievable. My son is threatening not to wear this anymore, he is fed up! Thanks... I feel slightly better now.
