Optimum review: Service with my cable box

I realized the search feature on my cable box no longer works. My husband called Optimum who said our samsong box no longer offer the search feature.. We made an appointment to have the tech install a different box - 2 - 4 on friday. Tech didn't show so we called and were told they would be here within a half an hour. Well that never happened, so we kept calling every half hour and were given different times each time we called. Finally at 8:00 we called again and was told the appointment was cancelled due to bad weather. There was no bad weather in Jersey that day, just a little rain. At 11:00pm, my service was shut off due to non payment of bill. At approxamately 11:20 we contacted Optimum again and told them our bill was up to date. We were then told that it was because of the new cable box that was installed today and we didn't pay for it. We told them the tech never showed and we didn't get the new box. Today a tech showed up with the same brand. We asked him to call the office to get someone down here with a correct box. He refused to call and left.
