Whirlpool products support is terrible

We purchased two top of the range Whirlpool products from Dionwired mid 2014. One of the products started giving problems and displaying errors after two month of use. When calling the Call centre to log a call out. They explain that they have a 72 hour SLA, however, after 72 hours and no response is received, we called again. The second call then take 72 hours to respond.<br> They also mention that the technician will confirm the time and day when he will respond. This too never happens. The technician just rocks up anytime and off course expects someone home to allow him access to your appliance.<br> The technician advised that our device required a part replaced and he would order it. This too never happened. after a number of weeks, several calls from myself, the service manager conceded to replace our product.<br> <br> In my dismay, we continued with the Whirlpool brand, up-scaled to the most released product, BUT to our horror, the process just started again. This took a little longer to surface than the first product.<br> <br> After several phone calls and irritations, the second product too was permitted an exchange. We decided to change our brand,
