Repeated Product Failure, Unresolved Service And Lack Of Follow-up

I own a De’Longhi EC9555 coffee machine and unfortunately experienced a grinder fault. I personally took the machine to an authorized service center, where I was told that a small piece of wood had become stuck inside the grinder and that the problem had been resolved. However, immediately after bringing the machine back home, the exact same grinder fault occurred again. I then contacted De’Longhi Türkiye by phone and email. I was informed that the machine would be collected from my home, but nobody came and I did not receive any effective follow-up regarding the issue, so I now have to take the machine back to the service center myself once again. Approximately three months after purchasing the machine, a second fault or warning appeared. I initially assumed it was a cleaning-related warning and therefore performed the recommended cleaning procedure multiple times. Despite this, the warning remains on the machine and the issue has not been resolved. As a result, I am dealing with a machine that has developed multiple faults within a very short period of ownership, a repair that failed immediately, and a promised collection service that never took place. For a premium brand, this level of after-sales service is extremely disappointing. I expect both faults to be properly diagnosed and permanently resolved. If the machine cannot be repaired reliably, I expect De’Longhi to provide an appropriate replacement solution. I will continue to update this complaint with any further developments until the matter is properly resolved.
