DINERS CLUB - INSTITUTIONAL *****; STUPID MANAGEMENT FAIL CUSTOMERS

I am a client for 30 years. They tell me to call encryptions so as to enable my cr. card to become 'smart'. I do so. Yet nothing changes. I mail them. No reply. Four times. No reply. After a week I call. No action. Call again. Management make promises. Guess what? NONE ARE KEPT. I get through to a senior. Guess what? He fails to keep his word. ****! After 2 weeks - malfunctioning card, no response, no accountability. ****my company
