Internet issues

I experience latency spikes of up to 500-1000ms every 10 minutes while I play Xbox for the past year. I have tried wired and wireless connections and nothing changes. I have moved closer to router, still nothing. I spoke with an ai bot who insists there is an issue with my internet performance and prompts me to schedule for a technician visit. I would like to know exactly what those findings were before I pay for a technician to not give me solution and fix my problem. I know for a fact my issues lie within this internet service as they do not happen when I am playing at another house or internet connection.
