Complaint Resolution Index (CRI)

Complaint Resolution Index (CRI) Explained The Complaint Resolution Index (CRI) is an indicator on how responsive a company is in addressing and resolving customer complaints brought to their attention by BCA. If they are considering doing business with the company, consumers can use this indicator to forecast the likelihood of having their issues addressed if a problem arises. CRI measures the company's customer satisfaction abilities through BCA’s complaint mediation process.

A variety of factors are considered when calculating CRI. This includes how quickly a company responds to complaints, the number of complaints against a company, whether the company addressed complaint allegations, and the outcome of the complaints. CRI is just a subset of the overall rating for the company. Consumers are encouraged to take into consideration the company's CRI, their overall BCA letter rating and other relevant information about the company so they can make a well-informed purchasing decision.

BCA's Summary and Analysis:

Our complaint history for this company shows that the company responded to and gave proper consideration to some complaints. However, most complaints are unresolved meaning the company failed to properly address the complaint allegations or their response was inadequate.

Stelo CGM - ID 1-02406341. The device worked correctly for about a week. Then, he jumped from about 90 to 240 blood level. In a matter of seconds. Then, continued to read at least 40 to a 140 points. Beyond my typical readings. It was obviously a complete failure of the device. And clearly beyond any normal ranges that I had prior to that device. My previous A1C test was 5.4. Also clearly inconsistent with their readings on the CGM. They refused to replace the device or refund the money. Resolution Sought I would like a replacement device for their failure or refund any of the money.I paid for the device

My name is Dior and I am filing a complaint against Stelo by Dexcom for unfair and misleading business practices. On January 17, 2026 at 4:50 in the morning I placed an order and noticed the shipping address was wrong. Within minutes, around 4:52, I used their chat box for help but no agents were available because it was the weekend. At 5:07 I submitted a support ticket. I acted immediately and well within their sixty minute correction window. Their policy says customers have sixty minutes to fix an order, but their support is closed on weekends which makes the policy impossible to use. Their system also did not show my order in my account so I could not cancel or update the address myself. When support replied on January 20 they said I missed the window which is not true because I reached out right away. They also incorrectly claimed I checked out as a guest even though my account was created at 4:57 during checkout. Because of all this the product shipped to the wrong address. I told Stelo multiple times that I still want the product and only need it sent to my correct address. They refused to fix it even though the issue happened because their system and hours prevented me from using the policy they advertise. I am asking the Business Consumer Alliance to review this. I acted immediately and the company still refused to help. I simply want the product I paid for sent to the correct address. Resolution Sought send me the item to the address requested
