I have been using Cargo 1 for many years and paid a monthly fee. Two years ago I have upgraded to Cargo 2 and have been since billed for both Cargo 1 and 2, which were all essentially linked to one website that I have with them. Upon noticing that and asking for a refund, they had offered a very poor customer service, noting no fault of their own as well as refusing to issue a refund for that obvious error and lack of transparency on their part. There are plenty of other website builders platforms that would own something like that. Very disappointed and carefully scanning all my payments from now on.
