I use my CIBC Costco Mastercard every day, everywhere. Online ordering is common for me. This week I ordered a vacuum to be delivered to my other address in London. My order was cancelled. Unbelievably, it's cancelled for using my cottage address on the card while my membership address is in London where tried to have my purchase delivered! I also reside there plus one other location in London. THIS IS NOBODY'S BUSINESS COSTCO. I was FORCED to comply changing my Mastercard address, my billing address and my membership address all match to use Costco.ca I am outraged they took my money, cancelled the order then made me change all these addresses to match even though all 3 are my legal addresses!! Costco doesn't deliver to my cottage so I sent it to my London address. Nope, only Costco insists to know my addresses match. Costco took $400 for my first order which I've paid. Now I just had the next $400. go through from complying and reordering. I now need to wait for the credit on my card for the original purchase! I am not happy they're playing with my money veiling it as security measures. How have I been using this card in Ontario, AB and Europe without being cancelled? I'm seriously considering moving back to my President's Choice Mastercard. I get a bit more in cash back with CIBC however this invasive transaction has my boiling that I'm here writing this! The vacuum is a great deal so I hope I don't get a dud on top of all of this.
