Its horrible customer service. At this point, I would tell them that they have 2 business days to provide a firm delivery date to you, or refund your money. I would also file a BBB complaint. When I was doing freshwater, I had a huge problem with an expensive Fluval cannister filter. Fluval CS basically told me too bad. I found their CEO on Linkedin and messaged him. In a week, I had a new filter, and they didnt want the old one back. Shipper damaged your tank, but the retailer and Red Sea should be all over this to resolve. I would make it clear that you wont be doing business with either of them any more. If the retailer happens to be a sponsor, I would message them on their thread here as well.
