Bad product and service

Bought a Hoover Bagless Cylinder vacuum at Makro 2 months ago. On the 21 of August the inside of the connection between the pipe and vacuum base breaks - you can't vacuum because the pipe does not stay connected. Today 24 Aug i take it back to Makro for a replacement piece of a refund. They refuse. The Hoover guy not in. They call the Hoover office - I must pay for the part. I ask why I must pay when it's only 2 months old and it cost R2000 - I only use the machine once a week so how the heck can it break so quickly. I am not happy and ask for the supervisor. She says the same. I refuse and I want to book it in for Hoover to check. And they take my details and tell me to write down the fault (must be in my hand writing ?) I can't seem to click on the rating below... I rate them 2 out of 5 because the machine worked perfectly until this piece broke and the fact that I have to pay for a faulty part that is not covered my the guarantee (ofcourse) after 2 months is pathetic!
