The whole purpose of this purchase was to install the filter in my travel trailer before my 3-weeks trip. The initial delivery date has been moved and delayed by 2 days. I made it clear to the support team member that I don't need the filter since it's delivery was delayed and it will arrive after I already left. Instead of emailing me a return label, a support person was trying to convince me it's not their fault and since there is nothing wrong with the filter, they won't be emailing me a return label and I have to cover the shipping cost myself. The attitude was absolutely unfriendly and totally not customer-oriented. Again: I don't have experience using the actual product, it is more about my frustration with the customer support. Since the return shipping cost is very high, I'm trying to sell it locally.
