Pathetic Service from Nashua Vaal

Nashua Vaal has been delaying the finalization of my husbands Estate. They have put a claim in against the estate. They have however collected all their equipment but they still want me to pay for the rental thereoff until the end of the contract. The contract was between them and my husband. the executor has requested a new settlement last year in September and they have not given any attention to this urgent matter up to this point in time. This is extremely poor customer service and I have no more patience with this pathetic way in which I am treated.
