I had a situation like this where I'd like to be involved in the meeting that I was requested and they thought I was required to be in. I'm a just barely above entry level employee and was told by my supervisor that I should not be attending the meetings anyhow the request is coming from project managers.
Finally get pinged in a meeting chat asking where I was and told them I was informed I should not be attending these moving forward. The project manager asked if this input came from a director that is 5 levels above me. I told them no, it came from my supervisor, if you need me, I will attend the meeting however I'm not sure if my input would be the information you are looking for.
2 months later, still getting required meeting invites but told by my supervisor to not accept it.
Sometimes the banks don't approve the chargeback without a police report. The police report needs to be filed. Also, if it still exist, try escalating onto best buy forums, you used to be able to get to their highest level escalation team by doing that.
