Propulsion System Charging Cable/cord Accessory problems of the 2020 Chevrolet Bolt Ev

I narrowly escaped a home and vehicle fire when my vehicle charging port received extensive damage from a mustart sae j1772 level 2 evse portable electric vehicle charger. The charging plug overheated and experienced meltdown. The mustart unit became so hot that my vehicle charging port charred and fused to the mustart charging plug. The charging head became very brittle, cracked exposing seals, and leaked oil down the vehicle charging port. Even though the charging head is now melted and broken, the charger does not register a fault, and still shows a green light if plugged into the wall. My first warning of a problem was the smell of burning plastic, oil leaking and what looked like smoke coming from the charging head. I immediately unplugged the charger from the wall, but could not remove the charging head from the vehicle charging port because it was fused to the car. I tried to shift the vehicle out of park and into neutral to move the vehicle away from my home, but the vehicle would not shift with the plug still attached. Even though unplugged from the wall, the bolt kept beeping, indicating an issue with the charger/port. Fearing a physical short in the charging circuitry of the vehicle, the burning smell and potential for fire, I forcefully removed the charger from the vehicle by pulling on the charging handle with full human stregnth until separated. The plastic parts of both the charger and charging port were burnt and broken. My chevy bolt was repaired by a licensed technician at the dealer, who blamed me for the charging fault and damages. Gm alleged the damage I caused to the charging unit during removal was pre-existing, causing a loose connection and short circuit. Gm refused to repair the damaged charging port under warranty, claiming user error and abuse. I sent a request for refund and reimbursement of damages to mustart on 8/05/2024 and will update this complaint after their official response.
