Dexcom review: Failed sensor

On 12/3/2023 I filled out a support ticket for a sensor giving incorrect readings, and not holding a calibration. On 12/4/2023 I was called back and the technician told me it was a bad sensor and to remove it and replace it with a new one. He then informed me because I had reached my limit of replacements in 90 days a replacement had to be approved. No emails came in approving a replacement. I called again on 12/5/2023 and was told it was still waiting to be approved and someone would call me with further questions. I have yet to hear from them. How are they able to tell you the sensor failed and remove it but then suddenly have to get an approval for a replacement on their failed product. I have used 45 sensors since January of this year. 4 out of 45 have actually made it the full 10 days without needing replaced or constantly calibrated. They do not care that their bad data causes my insulin pump to shut off insulin I need or causes my pump to give corrections I do not need, which then cause critical lows. This product is deadly and dangerous but refusing to replace their failed technology is the worst. I cannot wait until my pump is compatible with other CGM’s. Bad company, bad product and the worst customer service!
