You also have issues with lack of support from the franchise company--though without reviewing the franchise contract it is not apparent what support was promised so this may be a breach of contract issue or it may just be a bad business practices issue.
Finally, it seems you would like to continue in the business as an independent operator but have a non-compete in place that may affect your ability or right to do so.
You need some good legal advice. My suggestion is that you contact an experienced franchise attorney and tell your story. Most attorneys will do the initial consultation with you for free and if your case is strong they will often take the case on a contingency basis if you can't afford to pay them up front for their assistance.
