Florida Sunseeker

I ordered "Warm White" LED pool lights from Florida Sunseeker for my pool guy to install at my vacation house. When I came to the house, I discovered that the lights were not "Warm White," but as cool blue as a light can possibly be. They looked awful. I called Florida Sunseeker and they acknowledge the mistake in there product listing and they agreed to refund the full price of the bulbs and pay for shipping them back. I had to again pay my pool guy to change the lights and I returned them to Florida Sunseeker using the shipping label that they had e-mail me. I just received an e-mail from Florida Sunseeker saying that they were processing the refund (my credit card company has no record yet of them having done so) and that they were subtracting $20 for shipping. I called and e-mailed to request that they honor their word and refund the full amount of the lights. They refused.
