Genesis Hydrovac issue

Bought a Genesis Hydrovac Compact on 19 Dec 2025. The Vacuum gets used once a week to clean our small living space ( just my wife and I). On 28 Aug 2026, it decided to pack up on us, still being under the 2 year Guarantee ( gave off a serious burning smell with a weird sound). We took it back to Builders in Gqeberha, since it was still under Guarantee and not Warranty, we decided to buy a new vacuum thinking we'll get our money back once the old vacuum has been assessed. I don't want something back that smelt as if it was burning. Nevertheless, having already purchased a new vacuum because our home needed to be cleaned for the next couple of weeks while Verimark decided what they'll do, we get called on 19 Sep to collect the vacuum as its been repaired (after expressly asking for our money back because we bought a new vacuum on the day we returned the old one). Now what must I do with 2 vacuum cleaners Verimark? Was i not supposed to buy a new vacuum when I brought it back and was our home supposed to stay uncleaned until 19 September, almost a month later? We buy verimark to avoid this sort of thing but this is the second issue we've had with their products. First our steamer, where i accepted a replacement because it broke within 6 months. Now the vacuum. I wanted my money back this time because is this item expected to only last 7 months with usage once a week?. Nevertheless, you now have a client who is sitting with 2 vacuum cleaners (for what reason) that will never purchase any of your products ever again. Disappointed.
