Been a Costco Trade Member for over 15 years, but now having no end of problems with what was a fairly large online Order. Placed that on 11/05/2020, and paid in full, the funds leaving our Account same day. The Order was a mixture of main items that each included Carriage, plus a Grocery Order that included a single group Carriage. So far, so good. However, as the Order started to Ship, I noted Shipment Debits, IN ADDITION to the whole Order sum that had left our Account. I could see a Cash Flow drama about to unfold the moment the first Shipment Debit appeared, so contacted our bank and also Costco, all to no avail. Several hours on the phone to both, failed Costco Chats (cut off when I was number 1 in the queue), with neither the bank nor Costco interested enough to assist. We are down THE WHOLE ORDER VALUE, and Costco are now also busy Debiting every Shipment of the same Order, so DOUBLE PAYMENT. I appreciate this should square away, but it is not meant to work like this. Nobody else does this. We are now struggling to manage other Payments because Costco is busy helping itself to DOUBLE the payment. Latest was Costco now say I must email, which I did, but still nothing. You simply cannot get through to anyone who is in a position to assist. This is by far the worst experience we have ever had with Costco, and I cannot in all honesty recommend anyone use the Online System until this is addressed. It looks like Costco need to re-think how the Grocery Delivery option works with normal Online Sales. Right now, it does not work.19/05/2020 To reply to Catherine, yes, I had to get our bank to cancel the Authorisation, because Costco was ALSO taking additional sums as the Order part-shipped. There was no clearing down of the Authorisation as Shipments went out, so taken to the extreme, it was heading towards a situation that DOUBLE the funds would have been taken, before the original Authorisation was cleared down. Nobody else does it like this, and it is a nightmare from a Cash Flow point of view. This needs to be looked at by Costco. I have updated the score, because most of the Order has arrived, and there are no complaints in terms of that Service nor quality. The issue is solely a Billing Mechanism issue, which I suspect is linked to the Grocery Deliveries. A likely Workaround is to not mix items when Ordering, anything that includes Carriage, should be Ordered as a Single Order, even if that involves multiple smaller Orders. Then place a single Grocery Order that has a single Carriage Charge, and just hope that Costco do not take the sum twice over before clearing down the initial Authorisation.
