bad customer service I received trying to get help

I brought a microwave few months ago and now it's not working and it's less than a year since I got the microwave, I called to find out what should happen because its broken. Nd was transferred 3 times and all the ladies I spoke to were very rude, but funny the other one was even shouting at me as if I stole the microwave but of which I bought that on account, I'm shouted when I tell them their slip faded away as if it's my problem... What happened to treating customers with respect? Why is game employing such rude people....
