Costco

I bought 4 Inflatable float rings from Costco last summer. All 4 of them ripped at the same seam within the first time of use. I contacted you guys several times with absolutely no help. I was told to not return to Costco and that you guys would honor replacements. So I did that and replacements never came and I was never refunded either. I am very upset that over a year has gone by and now its next summer and still this issue hasn't been solved. I would like my 4 replacements sent immediately or I will have no choice but to escalate this to the Attorney general's office as well as the better business bureau. Attached is a picture of the deflated float and the model #. I bought 4 of them. 2 sets of 2. Thank you. Model # appears to be BWJSH00134.
