Samsung cannot deal with repair commitments

I bought a Samsung WW9000 washing machine last year. A top of the range signature product. The machine is no longer dispensing washing detergent. A call was made to Samsung to repair the fault. They sent a subcontractor to repair the fault. The subcontractor could not repair on site and arrangements were made to collect on Tuesday 3 May. Well Tuesday came and went and there was no collection. I got a call from some sleepy sounding guy on Wednesday to say he would collect today!!! Samsung SA I simply cannot take indefinite leave and wait until it is convenient for you to collect a machine after you don't make good on arrangements. I really thought Samsung was a top end brand and good reliable customer service could be assured. Instead you send a ***** unreliable appliance centre to repair on your behalf. This ***** repair centre cannot even collect a machine when arranged, how on earth can I expect them to repair a top end R 30 000,00 washing machine????
