Dischem DQUIP electric blanket controllers worse than cheapest Chinese quality

Dischem makes the worst electric blankets. I bought a king size electric blanket just over a year ago. My husband's controller stopped working just a few months after purchasing. We went into the store at the beginning of winter this year (N1 CITY CAPE TOWN) and asked to buy a new controller as we did not have a receipt from a year ago. They said they will try and source one and get back to us. They never did. We went back into store and called again but they always say they will source and never call back. Just before winter ended, the remaining controller packed up. We are sitting with a king size electric blanket, it cost well over a thousand rand, it's fairly new and of no use! They make horrible controllers that break so quickly. Why should we spend so much and buy a new blanket when clearly the blanket is fine, it's their toy quality controllers that need to be replaced. Dischem, this is peoples hard earned money. Get us the controllers so we can use this expensive product purchased from you!
