I ordered the deluxe calcium reactor package from the company Aquacave and When the package arrived On 05-29-2021 (I was present when UPS delivered it) I open the box to find out 2 piece of item are missing (the Carbondoser CO2 regulator and the CO2 cylinder) . I went on their site right away to file a missing item ticket. Now on 06-01-2021 they reach back to me to handle this ticket. After going back and forth with them, they said their employees sign off on the package before sending it to me. they said they sent everything out. Now I'm in the process of disputing all the charges and trying to RMA them all the items that "DID" come in the package.
