Attorney touches trust money without clients consent

I introduced a few buyers to 2 ladies working for the department of housing they said they were based in Braamfontein. The ladies names were Razia Lewis and the other Roslyn dons. My purchasers signed documents from the attorney that they said is affiliated to council known as Radhika ramdin Singh till today 2 years later they have not registered any plots and have not refunded the money paid to the attorney in her trust account. Everytime we call the attorney she refuses to take our calls and she also refuses to refund the money owing to the 2 purchasers that need to be paid. The two ladies Razia and Roslyn have also just gone quiet Razia does not answer any calls and when you speak to roslyn she keeps on saying that they will be refunding tomorrow. That tomorrow is 2 years now and still having a problem with the refunds.
