I contacted a number of purported "recovery" businesses after being struck by a rug pull on a DeFi platform, but the majority only offered costs without providing a strategy. It was just TONELIMITED.com that took my situation seriously. Real blockchain experts were employed by them to track wallet activity and report questionable addresses by collaborating with outside networks. They recovered a respectable amount of my ETH, but it took some time. If you're in the cryptocurrency space and have fallen victim to scams, these people are skilled at what they do.
