Misleaded and Disappointed

I had purchased a Defy Matalic Microwave DM0390 16.10.2020 from HiFi Corp Springfield being told it's a 2 year warranty. 2 weeks ago the globe/light in the microwave stopped working and last week it started tripping my electricity every now and then. So I decided to return the product as it was still under warranty. I get to the store only to be informed it has a 2 year repair warranty. Now that was never told to me in store upon purchase and neither does my till slip state that. I was also informed that it takes up to 21days for the repair to be done however HiFi Corp informs their customers of an up to 14 days waiting period. I run a creche from home and a microwave is essential to my business and my everyday life as I need to warm the meals the kids come with. I'm very disappointed to learn that warranties change to suit the service provider and should I was informed upon purchase of this I would have never purchased that microwave. I was even prepared to buy that display Microwave as there was no stock in store and at the full price which I did scratches and all on the microwave. All my appliances are Defy and I know it's a trusted band but to be told this now and having to have no microwave is really disappointing and I feel misleaded. We as consumers need to be told about all T's & C's so we give the fair choice to make the purchase as we are paying for it not to be misleaded just so sales can be made.
