Would like to give 0 stars. Wait for an exchange of a disk for a year. After about 10 months then finally came the company Wigger over. Unfortunately, the disc did not fit. If one expects that short-term replacement will be delivered, one was wrong. The spare disk was unfortunately damaged by a warehouse worker with a forklift. Wait again. Finally, after several weeks, a new date for the exchange was agreed. The date agreed for a Wednesday was not noticed. After a call to the company Wigger it was said that not Wednesday but Thursday is noted as an appointment for the exchange in the system. It was once again excused and the next day as a Monday appointment firmly assured. However, on the next day nobody from the company Wigger came over. No call nothing ....
Since I had to work on the two days, I asked an acquaintance to accompany the exchange and the fitters of the Fa. Wigger open the door. My friend sat as described on both days for several hours with me in the apartment in the hope that maybe still a fitter appears. In vain....
I am completely disappointed !!
