Cancer patient waiting now for the 2nd week , still no Service.

Yesterday, the technician called and said he is just waiting for a part. Then he will come trough for the repair. He arrived, with No part. Just drained the water, and said, it should work. When I asked, where is the new pump, he said, he forgot it at the office. He will be back with the part today..... Today, my phone just gives one ring from a 011 nr, before I can answer the phone, it shows miss call.... When I enquired on WhatsApp, they said. We try to call you 3 times. But you don't answer. This is becoming ridiculous! Even after I begged them to sort it out, with my wife's cancer, I MUST wash her bedding and clothing every 2 days.... Its been more than a week now. And Samsung is just playing games.
