I have been a customer of Costco Water Delivery by Sierra Springs for 3-4 years. At first, customer service was great. But in the las year to 18 months the website has changed at least twice blocking my access to web service and it has been extremely difficult to contact CS by phone. The automated scheduling service is ackward and not reliable. I've gotten System is down message and greater than 15 min hold by phone. What gives?
