AAMCO Transmissions review: Car storage bill of 420.00

I brought my car into AAMCO on Tuesday to have the transmission repaired. The car was parked there for a week and each time I called they kept telling me that the inspector did not arrive. I have maintenance insurance with Protect My Car. A friend of mine called me and told me that she had a friend that owned a transmission garage and he is willing to fix my car for $3, 600 as opposed to $5400. This was a huge difference in price. I called them to tell them that I was removing my car. When I went to pick up my car, I was informed that it would cost me $70.00 per day. There is a sign in the office that says $70.00 for storage per day, but this sign is off to the far left of the Office instead of up front where it should be viewed by all costumers. I feel should be stated when the person is bringing their car in, and the 2 men at the front desk agreed. The total bill came to $658.00 when they really did nothing. I don't object to paying for the diagnostic, but I ended up paying $420.00 in storage just to have my car sit there in the grass in outside parking lot. Since I am unemployed at this time because of Covid, I am wondering if you can help. Thanking you in advance, Marylou Wing, phone [protected]
