Annoyed with Makro Service

I am more than disgusted in the after sales/repair service I have received. My daughter bought me a Nescafe Alegria 2 A510 Coffee Machine from Makro (Silver Lakes) for Christmas 2017. I opened it on Christmas Eve of 2017 - assembled it - and nothing - IT DID NOT WORK. So it went back to Makro (Silver Lakes) and they replaced it with a new one. I had to return this Coffee Machine to Makro on 02/04/2018 as it again would not work. Makro sent this machine into the Manufacturers and told me that it will be ready for collection in 6 weeks or less. Well it is still not ready for collection !!!!! When you contact Makro they love to keep you on hold or just drop the line after holding more than 15 mins. I am deeply annoyed and would like a new Machine. Susan
