You can rest confident that nobody at NOWtv cares one jot about fixing the problems. I speak from experience of numerous 'chats', each trotting-out the standard assurance that the issue will be referred to another department and resolved within 24-48 hours. Each time, NOWtv state adamantly that I will receive an e-mail advising any requirements. No e-mails are received, nothing is resolved. NOWtv simply want to take our money, hide from direct contact and do nothing. In the absence of integrity or a desire to ensure customer-satisfaction, why should they care? They already have my money without having to provide any level of service. They must be so proud of this formula, because they never change it.
