Shop situation??? Advice please.

[Grnova]

Hello everyone have a dilemma and need some help!
I took my vehicle out of state to have a few things buttoned up that I did not have time to complete myself! I met with the shop owner and we went over what I needed complete and told him what my budget was. We agreed on monthly statements and was told I could access the build progress on line. I was also told he was going to send me a list of things we had discussed.
Well, one month went by, I called and asked about progress and an invoice, I was sent a few pictures in a text and was told they didn't really work on the car much to produce an invoice. The next few months I tried to meet up with him but he was either busy or out of town racing and couldn't really get together. Had him do a mock up for a part he needed me to purchase. We kept in touch over the months a few questions on my overall plan for the car questions about items I need to order. Six months later I finally receive six invoices all at once, And around 116 progress photos. And also a bill for almost double my budget without any one item fully complete. And over 2/3 of the invoices were labor charges. Up until now I have not paid any amount of money.

Now when I talked to the shop Owner and tried to ask why I was being charged an hourly rate instead of my budget. I was told that he does not remember talking about a "budget". And was also informed that a new shop manager was brought on and that I should talk to him. So I called the shop manager and he was told to send out the invoices and that he really knew nothing about the agreement I had with the shop owner. This is why I wanted monthly invoices as to what was complete. After looking over the invoices I just got , I noticed that 2 months after the initial meeting I had already burned through 2/3 of my budget. I still had 4 more invoices to look at. I need ADVICE where did I go wrong? What's next? How can I get my car back?
