Highland Capital Group LLC review: My friend wasted money, because this company hasn't transferred money

Don’t do any business with the company Highland Capital Group LLC. My friend spoke with the representative of the company and they agreed that the company would give credit to my friend. He has even paid the deposit and the sum was rather high. But the company failed and no explanation why. My friend hired the attorney and the process started, so my friend has wasted another sum to get all papers and money back from these guys.
