Very poor experience with customer services. The return of the item seems almost like an impossible task. Have been on the phone 3 times (waiting time to speak with someone is over 30'),the staff is very unhelpful and in a way rude, they put the blame on the supplier who has not been in touch to organise the return (although the purchase was through Costco and Costco should deal with the return from the customer and they could then deal with the supplier). It's been 2 weeks with no progress at all. Costco has proven to be a big let down with appalling customer service when it comes to returns
