Took my money and ran

I accidently overpaid them ( Hilton ) after they built a nutec home for me. However after informing them of this, they " had to look at the quote first" and since then I cannot get hold of them. These two brothers have now blocked me . So disappointed!! Money was paid into Ms P. Temmings account but the company is Nutec Housd Cape Town. 1 Brother is called Hilton and the other I think Faizel. Do NOT DO BUSINESS WITH THEM.
