No customer care

The on button of my washing machine gave problems. I bought it online from Macro and it is still under warranty but they said I need to contact Defy. A technician came, said they need to replace the switch and said that he would come back the next day but didn't. After a month I contacted them again, just to hear that a service call was logged, that they are waiting for a switch from abroad and that it will arrive in 6-7 days. I am now waiting for 10 days and still no technician. I am without a washing machine for more than a month!!
