When the extractor fan in our oven starting making horrendous noises we called Miele. Miele products can only be serviced by Miele engineers which limits you to their fixed price repair or standard call out fee. I spoke with customer service and explained the issue and advised it was an older oven as wanted to check parts were still available. They arranged the visit for the next day. I was very impressed. Miele called back to explain having spoken to a technician they needed to order the part in. Visit rearrange for the following week. The technician arrived, replaced the fan, advised the oven was fixed and left. I used the oven shortly after and within 5 minutes the same problem occurred. I texted and called the technician explaining the problem was still occurring and asked if he could return. I was asked to send a recording of the noise. From this recording he diagnosed it was actually another extractor fan that was faulty and this part was no longer available! My oven is beyond economical repair less than a week before Christmas! I was dissatisfied as the oven had not been serviced properly or tested and requested a refund. I was offered a partial refund. I called customer service to explain the service had not been carried out properly. After a long time of being told the service had been carried out I asked to be escalated to a Manager. I was told to expect a call back in 72 hours. No call back, so I had to chase. Again very poor customer service from the Manager I spoke to. Now awaiting another call back after they have spoken with the technician. Miele are extremely poor at dealing with dissatisfied customers. Still waiting for a resolution. No offer of help or guidance from Miele. They no longer make double ovens so can't even use the money against another oven. However, after this experience I would never purchase another Miele appliance.
