My dishwasher has been written off, and the insurance are sending me a voucher for a new one. Anyway had a call today from the engineer who fitted a new pump yesterday, and he wants to come and take the pump off He said its because he hasn't been paid for it, and he has to send it back to get a refund as now the dishwasher has been written off he won't get paid!!?? I was so taken back I agreed, but that is my property so should I allow him?
