"there is nothing deceitful, pretentious, or alterior motives going on here. We don't blame anybody for my husbands ill health. But when somebody doesn't honor their word or contract, why be quiet about it, when lack of integrity has an impact upon somebody's life?"
And there's the problem. You don't blame them for his health but you are blaming them for his health? Your complaint is that they could not provide a timely tow, end of complaint. Your and your husband's health is something that is your responsibility to take care of. That is all people are saying.
