Shockingly terrible service!

I reported my dishwasher as broken on 6th March. I had to pay R400 UP FRONT for a service technician to confirm it was broken. I then had to follow up 3 times for the quote each time I was PUT ON HOLD on my cell phone for over 10 minutes only to be told someone would call me back later with an answer. Each time I was called back with a different EXCUSE as to why the quote was taking so long. I eventually got a quote OVER A MONTH later then finally the technician arrived to change the part. The next day my dishwasher was STILL NOT WORKING I had already paid a further R1600 for this part and immediately called last week Thursday to let them know it was still broken and I have yet to be contacted by the technician which means I now have to follow up YET AGAIN!!! It is now the 20th of April well over a month, many phone calls and R2000 rand later I still have a broken machine!! I am furious and have NEVER experienced such TERRIBLE SERVICE. I will NEVEr buy another WHIRLPOOL product I feel they have ****** my money!
