Complaint Review: Sparkletts

I started Sparkletts water about 3 months ago, at first service was great and then they kept not delivering water when they said.  One time they picked up 5 empty bottles and did not leave 1 full bottle.  And before you say it I paid every bill on time thru electronic billing.  I called a total of 16 times, was on hold a total of 3 hours combined and talked to 3 managers.  All of who promised to get everything straight and get my water delivered.  The last manager named Chris called me last Thursday (9/8/) and Promised me for absolute sure that 5 bottles of water and 2 free cases (because of all the mistakes) would be here Friday 9/9)  They also had a cooler to pick up as we had purchased our own because after 3 coolers you still could not hear the TV for the noise of the cooler.  Well guess what?  It is 9-15-16 and after 3 more phone calls this weeks I still have the cooler and the 2 empty bottles.  We have switched to Arrowhead and they were here as promised on Tuesday.  We purchased this water service from Costco and this is the first time in 20 years I have had a problem with Costco.
