I scheduled a pool opening with ADI. I called the day before to verify they were coming. On the scheduled day nobody showed up by 5:00 so I called several times but all you get is an answering service and they have no idea the situation, and you leave messages which are not returned. I finally got a call about 7 pm, after 2 emails, 4 phone messages left saying they are running late but should still be there, so we waited. nobody every showed up. So, now it's saturday, we have company coming over, and I call them 3 more times, and only get the service. I finally get a message saying sorry they ran late, and i could reschedule for Monday. I understand if things run behind and they did not get there on friday, but I should have then been the first person to schedule on Saturday morning, not 3 days later... I left several more messages and emails with no response. I finally had to spend most of the day opening the pool myself, since there was no way to book anyone else that late.
