Makro run around and Aro replacement parts

I purchased an Aro 20 liter water urn from Makro that is now outside of warranty. The urn now needs repairs in the form of a new lid, since the current one has perished, It also needs a new thermostat. Makro seems to not care about products they sell to the public when outside warranty. I contacted Makro to obtain the agents of the said product details. I was given a number to contact, of which I did, only to be given another number by the person from the Makro supp**** number. I feel after the third number that I've been given the run around and Makro don't care, I think they just want you to buy another water urn. If this is the attitude of Makro then I'll spread the word never to shop there again. Firstly I want to know who are ARO, How they can be contacted and where can I get replacement parts for their products. If a store sell products then they should have all details about suppliers for public consumption
