My G6 sensors and transmitter supplies was delayed by 6 weeks due to the incompetency and neglects from DexCom Customers service department. DexCom's employees had no knowledge of the insurance company policy and kept giving me false and inconsistent information. I changed my insurance company Sept 2020, and when I called DexCom to reorder on 09/14, I was told that they needed to verify my insurance. I called three days later, and was told that my insurance approved it, but they needed my doctor to provide a new prescription and a medical necessity form. I spent over 10 hours in the period of three weeks to work with DexCom and my PCP to get all the forms ready, but I was told that DexCom was out of network and if I ordered through DexCom, I would have to pay out of my own pocket. However, I could go to one of DexCom's distributor, EdgePark, which was in net work with my insurance. On 10/02, the specialist, Blanca told me that she would forward all the paper to EdgePark to proceed with my order, but I would not have to go through the whole process again. I called EdgePark to place my order 5 days later, and I was told that they only got a referral from DexCom, not the prescription and the medical necessity form. In order to place my order, they needed my doctors prescription and the medical necessity form again, which could take up another 15 days. Despite the fact that I told them I was out of sensors and transmitter for over a month, and I have been having hypoglycemia 2 or 3 times a day, and almost got into a car accident because of that, they still insisted that there was no way for them to escalate the process. Also, the customer service rep told me that I am supposed to have a specialist working on my account to help me get my supplies on time, but I never heard from that specialist. What is even worse, different customer service reps told me different names of the specialist, and there was no way for me to find out who is the real specialist, or if I actually have one. DexCom is lucky to have great engineers working in the company to make good products, but the customer service team is the worst in the world, and many of them don't deserve a job because what they care is whether they could get a paycheck, and not helping the patients. And I couldn't even file a complaint with them because they are covering up for each other.
