We bought a new oven from currys and were pressured to use knowhow as the installers. We paid £100 for this. The knowhow installer used no protective floor or unit covers, and as a result he damaged our brand new kitchen units during the installation. He also left muddy footprints throughout the hall and kitchen, and left assorted debris in the kitchen and across the drive – even though we had paid extra for them to remove all debris. When I complained to currys they said it was not their problem as knowhow are a different company, and passed me to their customer care team. Currys then ignored all contact from me. The knowhow team were useless and treated me like the damage was my fault. It took ages for them to initially respond, and months of me chasing to get to a resolution. Knowhow took no responsibility and did not help at all. It was up to me to find and then contact companies to repair and replace, and send these to knowhow. They even had the gall to inform me the quotes were in the wrong format! I had to constantly fight in order for our kitchen to be restored to its former condition. And received nothing from knowhow with regard to the mess and the debris. And they would not reimburse the installation costs. A shocking way to treat a former customer. Problems happen, but it’s how they are dealt with that shows what kind of company they are – knowhow have absolutely no interest in customers or their property, and have no follow up when there are problems. There are many other companies providing the same service. Use knowhow at your peril.
