Xiaolong Zhang and his wife sold their auto parts distribution business in Vaughan, Ont., at the end of last year to fund their retirement.

They said they hired Ping-Teng Tan to handle the sale because they trusted him after using him for previous legal work.

The business sold for more than $520,000 and the money was transferred to a trust account set up by Tan's law firm, Tan & Associates.

But, despite calls, texts, an in-person visit and a legal demand, Tan hasn't transferred the money to Zhang and his wife.
