Poor service from employees and managers

On the 3 April I received my invertor back from repairs from the Riverhorse ACDC, I called them on the 4 April to advise that I only received one cable which was the power cable. I had another cable that was handed in. Called again on 6the April, 12 April and spoke to Kaylin, I was told over and over they would get to the bottom of where my cable was. On the 13 April I called and spoke to manger Frank. He promised to call me back with a solution and I am still waiting. I decided to go buy a new cable and I went to plug in the Invertor to charge and the power cable given originally on 3 April is the wrong one. So now I have to spend more money to get that replaced. I am disappointed that I had to spend R2500 on requires, R250 on a cable they lost. And now spend more money on a new power cable as they sent the wrong one, disgusting service.
