MetLife - Auto Insurance Customer Service Issues

Hello, I am Christopher Adams, and I currently have dental and auto insurance policies with you under #[redacted]. I have been a customer for almost 4 years for dental and close to a year for auto insurance. I renewed my policy for an additional 6 months in February of this year, and it was up on February 24, [redacted]. I paid my full premium of $1,[redacted] after speaking with a representative who guided me through the process. My autopay was stopped as I requested since I paid in full. However, unexpectedly, four months later in early May, I received a bill stating I owed over $[redacted]. I was never informed about any additional fees, and it was a surprise to me. I tried to resolve this with a customer service representative, but I found the assistance lacking. I value your insurance services and was planning to continue with your company long-term, but this experience has left me disappointed. I hope this issue can be resolved promptly. Thank you for your attention to this matter. Respectfully, Christopher A.
