Karcher at makro

I have purchased a karcher k4 classic pressure cleaner within a month the hose started leaking water and I was advised by makro staff that hose is not under warranty so I purchased a new hose. Two months later the machine stopped working I took it to repairs at the Polokwane branch and was contacted 4 weeks later with an sms saying I needed to pay for the cylinder head to be repaired I contacted makro call centre and requested further information as to why the cylinder head was not covered by the manufacturer. I was told that makro would call me back after discussing with karcher. I visited the store a month later and requested an update to which the staff New nothing about and told me they would call me during the week with not a single call. I visited store after 4 weeks once again and they told me the manager can't assist at that moment because he was busy and they would call me after discussing with him it's been 4 months on going with this misrable service from makro and karcher. I even advised them about the fact that I was using the machine at home to clean my vehicles and paving but they have not even had the decency to give me an update on machine I am extremely frustrated dealing with this group!!!
