Poor unacceptable service from Miele

Dear Miele Customer Service,

I am writing to express my dissatisfaction with the lack of communication and the time it has taken to repair my appliance. Firstly you required a call out fee of R1100.00 Then you charge a diagnosis fee of R647.00 And lastly you charge a repair cost of R3508.00 Furthermore nowhere on your cost estimate does it inform the client to make a per-payment before the repair. I discovered this a week later when it bought to my attention after sending an e-mail which was never responded to, so I had to call your service department. Furthermore, your exorbitant repair cost and the process has taken significantly longer (in total 4 weeks), causing me considerable inconvenience.
