Hello from California major problems here.
I think the fact that they knew it had a bad wire and they didnt check/double check all the wires afterwards shows they have less compitence than they probably should. maybe list everything you can think of on here in the proper forum, everything thats happened, in chronological order with whatever details you have, and use the knowledge of the community to HELP the shop fix it for you. The most experienced mechanic can over look a simple issue trying to think about all the complicated fixes, i do it with my cars and computers all the time!
btw welcome..Im new myself..but seems to be a great community and I guarantee you, you will find the answer here if one exhists

*btw...document dates, times, people you spoke with, phone conversations, etc and get as much in writing they claim they are responsible for. a lawsuit is only as strong as its evidence.
