12 Month Guarantee but want to repair it

Good Day,<br> <br> We bought a small stove in January. It clearly states there is a 12 Month Guarantee on the box. The one plate switch on by itself and we took it back for a new one today. <br> <br> We were told that they can only fix it. The manager who assisted us wasn't very friendly hes name is Warren. The lady (Karen) who checked the stove had an attitude and told us to plug out the stove at night it will solve the problem of the one plate going on by itself. <br> <br> My understanding of a guarantee is that the item will be replaced in that time period and a warranty the item will be repaired. I would like a new stove or my money back. I have contacted the consumer protection act as well. The manager couldn't provide me with one he said they use to have one up by the customer service. Thanks
