Returned my dishwasher with pieces missing, then avoided my calls

<p>My dishwasher required a PC board replacement. I contacted Goldtech Electrical and Appliance Repairs, and they came out, took the dishwasher away & fixed it, charging me just under R2000. I was happy until I realised the top tray's retainer pieces were now missing.</p> <p>A call to the business owner got me vague promises to bring them back, which never happened. Suddenly he and his partner would not take my calls and emails and now, more than a week later, they remain uncontactable. Funny how contactable they were when they wanted their money - which I paid promptly (same day). Their guarantee means nothing...</p>
