I assume you are talking about your A1C % results? If so, that is diagnostic of type 2 diabetes (greater than or equal to 6.5%). They should have picked up on that. Likely your doctors dismissed the numbers as they are barely in the diabetic range, but they should have said something. The same thing happened to me. You need to take this seriously and work to get your blood sugar levels lower. You need to get a blood glucose meter and start testing yourself to figure out what your blood glucose levels are throughout the day - in the morning before breakfast, 1 and 2 hours after eating, etc. I doubt a complaint would do much good, but maybe ask your doctors why they failed to recognise that you had A1C levels in the diabetic range.
My A1C was only 6.5%,but I got nerve damage in my feet from my high blood sugar levels. Now it's under control with a low carb high fat diet.
Good luck.
