Smeg poor after sales service!!!

We bought a Smeg Extractor fan in July and when we had it installed it was discovered that the unit was faulty. We've reported this immediately to Smeg customer services and waited for almost a month before a technician came out to inspect it. When he finally came out he said the fan motor was faulty. After another month, and numerous follow ups, the technician came to install the new motor, only to discover that it was not the motor that is faulty, but another part. After another month of waiting, the tecnician came out again, without the part that was faulty. It is now 3 months after we've bought the unit,but cannot use it at all.
