I purchase a IMac computer from Costco.com and the order shipping process has been a nightmare from day one. The order was placed Mar10 and the money over $2000 was deducted from my checking acct. that day. Three days later I checked the shipping progress and found their system rejected the way I wrote my address (Apt 3 instead of Apt C ,which I was told how their system identified my address). My bank said nothing was wrong with the address I used and ad already paid Costco. I called Costco back on Mar13 and asked them to deliver the product to the updated address but they told me they canceled the order and told me I would have to replace the order. The only problem was: 1. my bank had already released the funds to Costco, and 2. a $150 promotional discount had expired which Costco then told me they would refund within 5-7 days once I placed the new order. They also said the would refund the $2000 for the original canceled order. I followed every bit of advise Costco gave me and reordered that day. However, Costco charged the funds for the new order right away while the additional $2000 for the original order still sat unavailable to me for several days. On top of that, the $150 promotion still has not been returned to my account by Mar28 despite my calling in several times between Mar13 and now. I have received different information each time I call in with the latest admission from their customer service being that they had to "fill out a form" for the credit to my bank which was actually "turned in March 24th" and I will have to wait another 5-7 days until "my bank accepts" the credit. That makes no sense and when I asked why hey did not turn in the form to my bank until March 24th, they said it was because it was over $100 and had to "go through a supervisor". I have yet to see the money all the while Costco held double the order amount for days and now holds the $150 for several more weeks!!! Unacceptable! Their online service stinks!
