Dexcom G6 Supplies

Hi all... I have been on healing well for many years under Prostate Cancer forum, but first time on this group. I have non-diabetic hypoglycemia for past 6 or so years. My endocrinologist put me on the Dexcom G6 about 3 years ago due to hypoglycemic unawareness. It has worked well for me but recently Dexcom told me they were switching me over to another vendor to order supplies. ADS in Carlsbad CA. Well... it has been a terrible experience. I ordered my transmitter 2 weeks ago and still haven’t received it. I have called them 3 times in last 3 days to order more sensors and they say they are really busy and will call me back. No call backs. So any of you use a supply company for the G6 that you like? Thanks for the help! JR
