NO service from DeLonghi

We bought a Coffee Machine from Dion Wired for plus minus R20 000 for our Office. The machine started making a loud noise, so we called Deon Wired in November 2016 to organize the repair. We had to take the machine back to Dion Wired in the Grove and they sent it to DeLonghi. We received an invoice and paid R1800 for the repairs and they delivered in January 2018. The machine was still not working. After numerous discussions with SILINDELE BUTELEZI (whom should not be dealing with customers), I called Dion Wired again. The machine was delivered today STILL not working. Three months later and they can't fix their own coffee machine?? Can I suggest that they test the machine before sending it out. The most frustrating part is that there is nobody to complain to, they just pass the buck and make you more frustrated. How can they operate a business without any customer service s****s! My advice to everybody who might be interested in a DeLonghi machine; please don't buy anything with the DeLonghi brand.
