Smeg Dishwasher

We called them to replace our Smeg Dishwasher pump, the pump wasn't working anymore. They fetch our Smeg Dishwasher and about 3 weeks later they delivered it back. After the fisrt use we noticed it doesn't warm anymore. We called them again, they picked it up again. After a week of no communication from their side, we called to ask if they have a update. No said the women their still searching she will let us know what it will cost. (In the fisrt place it worked before we send it to them, now we need to pay again for something they broke) after 2 weeks passing again, no answer from their side. Call them again, no their still searching, they will order parts. It's more than a week later, still no answer.
