Service Centre, what service?

Our dishwasher showed an error code, we contacted the Service center who referred us to the "local agent". He was unable to fix on-site so removed the machine to his workshop for further investigation. He quoted over R4500 to repair with vague information as to what he needed to do. We asked the Service center to review his quote, three weeks later and still no progress. No return calls from the Service center in spite of promises, our letter to Peter Brownlee went unanswered. Apparently as we "did not accept his quote the job card was closed" and the Service center said they "did not want to open a can of worms!". We eventually retrieved our machine, which still does not work but had to pay R1500 CASH before he would leave our property. This for parts which he said he needed to test the machine but it transpires he already had in his workshop. Absolutely appalled at the attitude and utter lack of professionalism of all concerned.
