Absolutely terrible customer service / Purchase aftercare

I live in apartment with all SMEG appliances, the whole building (all 20 floors) has the same appliances and finishings. My washing machine stopped working mid-cycle and refused to open as the filter needed to be cleaned. I called this in, they said they would send someone in 3 days. I have my whites stewing in warm water in the interim. The technician arrived today, looked at it for 3 mins and said he couldn't reach the pump because how it was encased in the kitchen cupboard. Every single apartment in this 20 story building has the exact same finishings and I assume the building is one of their biggest customers. They simply told me to call the cupboard people and call them back when they've fixed the cupboard. They have serviced this building for a year and should have known the setup and organised with whoever they were supposed to liase with. My clothes are going to be ruined and I cannot believe it should take a week to clean the filter of a washing machine
