Business ProfileforDelta Dental of California Enterprises

Delta Dental has denied my recent dental claim (Case ID: ***********, due to the plan waiting period requirements. This waiting period is six whole months!In my case, I enrolled in Delta Dental while I was working for a large company in 2022. I left that company on April 15 of 2022. I continued Delta Dental insurance through enrollment in California COBRA. This coverage continued for another 18 months until it expired on October 15, 2023. On September 26, 2023, that is couple of weeks before my COBRA coverage ended in month of October, I contacted Delta Dental by phone and requested that my dental coverage continues after October 15th of 2023. The sale representative advised that I must enroll in a personal plan which has a higher premium. I agreed and the sale representative provided a brief outline of my coverage, including $50 deductible as well as coverage for all preventive care, two times a year. The sales representative never mentioned the 6-month waiting period requirements! I provided my credit card number, and I was charged $139.84 that included $10.00 Enrollment Fee and premium for the next two months. I received a letter from Delta Dental including the Insurance card, indicating Payment received since your previous bill -$139.84. Note that my previous bill to Delta Dental was through COBRA coverage. I was glad that I had all the basis covered and that my dental insurance was/is continuous from the last company to COBRA and then on to my personal premium Delta Dental Plan.Now Delta Dental says that my effective Dental coverage was set to begin December 1, 2023! That goes against their own policy writeups! Is this just/right? Delta Dental must honor its obligation to fully inform its customers of their coverage requirements not only through their sales representatives but also via mailing their contract requirements, giving reviewing time and enabling customers to agree/disagree with its terms.
