Poor service from Karcher

We bought our Karcher FC5 from Makro. The Karcher started leaking water and we handed it in under warranty. It's been more than 4 weeks and Karcher is still waiting for spares! I logged a complaint with Karcher's customer complaint platform - what a joke. No response. So, the customer must just wait until Karcher finally fix it. This is pathetic service and I will defenately not recommend this product.
