DEFY - NOT SERIOUS ABOUT THEIR CLIENTS AND QUALITY

I AM CURRENTLY DISGUSTED IN DEFY PRODUCTS AND THEY AFTER SALES SERVICES. BOUGHT A DEFY DISHWASHER ON 15 APRIL 2018. 41 DAYS LATER MY DISHWASHER DOOR DID NOT WANT TO CLOSE. I LOGGED A CALL 28 APRIL 2018 AT 08:00 WITH REFERENCE NUMBER 911275 AND AGENT PROMISED THAT I WILL BE CONTACTED WITHIN 3 DAYS. THIS MORNING I PHONED AGAIN STATING THAT IT IS THE 3RD DAY AND STILL NO TECHNICIAN CONTACTED ME, I WAS TOLD SOMEONE WILL CALL ME FRIDAY. I INFORMED THE AGENT THAT THIS IS NOT ACCEPTABLE, DEFY SAID WITHIN 3 DAYS AND I PAID CASH FOR MY DISHWASHER I DID NOT ASK THEM TO WAIT FOR 5 DAYS FOR THEIR MONEY. SHE THREW DOWN THE PHONE IN MY EARS . DEFY IS THIS YOUR SERVICE AND QUALITY??? THIS IS MY FIRST DEFY DISHWASHER AND I AM THOROUGHLY DISGUSTED!!!! I WILL NOT BE CAUGHT DEAD BUYING ANOTHER DEFY PRODUCT AND I WILL INFORM ALL WILLING TO LISTEN THAT YOU SUCK! AND THAT YOUR AGENTS ARE RUDE! I HAD TWO KELVINATER DISHWASHERS PREVIOUSLY AND EVENTUALLY HAD TO REPLACE THEM DUE TO AGE AND NOT DUE TO NOT FUNCTIONING!!! WHAT IS WRONG WITH YOU PEOPLE?
