Poor service from Sandton @Home

I took my Breville juicer in for repairs in July. I met with a gentleman Byron Botha who assured me he would send me a quote on the repair work. I had to phone him several times in August to find out the cost of repair. I did not get any joy as he was not at work or he stepped out. I decided to go to the store in Sandton and spoke to his colleagues and they assured me that when Byron is back they will give him a message and will ask him to call me. I waited a week and still did not get a call from Byron. I phoned him again several times until one day he was in store and took my call.he told me he has not got any reply from his service provider and will let me know the amount. In September I went to the store and asked for Byron and as usual no Byron. I phoned again in the week and he returned my call giving my wife a ridiculous amount to do the repair. So I went to the store and requested that they can get my juicer without it being repaired. We are now in October and I still don't have my juicer back. I don't understand how an employee of such a big company ignore their customers. Surely there should be checks for employees performance. This guy is the last guy any company should employ because of him incompetence.
