AAMCO Transmissions review: Do not trust them

I am a single mom who had just paid off my 2021 ford bronco and was faced with the decision to trade it in or replace the transmission... Aamco in sugar hill confidently provided a verbal estimate of a complete overhaul of no more than $7k. This "confident estimate" increased to over $9k claiming the damage was more extensive than they thought. They finished within a week, but my check engine light continued to return as did I to allow aamco to fix it correctly, but this resulted in over three visits for further repairs (for performance and noise concerns)... Given vague explanations as to what was wrong... Check engine light still remained on but codes were exhaust related so I did not assume this was due to the transmission replacement but last week the vehicle suddenly sounded like the muffler was falling off and I could not accelerate smoothly so I took it to another shop that diagnosed it as a catalytic converter issue and found that the support bracket for the catalytic converter was completely missing (the oem part has it attached). This repair cost me another $2k. I have several unanswered text messages to the regional manager explaining my concerns about the integrity of their repairs, I have videos of engine noises, and my check engine light remains.
