ok I have never stayed at the dolphin but have worked for a major credit card company. First of all some debit cards have the visa logo, if you have this type you still get charge back etc.,....Secondly holds on the account are normal. The charges do not come off till the "official"bill is received. Thridly, lots of charges(or holds) for the same amount is normal, happens all the time. Machines are touchy and sometimes merchants think it hasn't accepted and they hit the "enter key" mor than once. When the "official" bill comes in everything else comes off. I'm sorry this effects your bank account, to often people don't understand how these things work.
None of this appears to be dolphins fault. You really have to wait the full seven to ten days and then check what was actually charged, before panicking.
If after that time you have actaully had an error then dispute it , or call dolphin.
None of what you've described as far as billing appears abnormal to what I see every day. Yes, there is always someone who calls us confused about the holding process, but our hands are tied until the signed bill comes in. I once had a woman who owned a flower shop call because she couldn't charge gas on her card. I looked at her account and there were huge holds on her account from a flower shop. She said "oh, I was just seeing what my available balance was" I told her well now because she did that she tied up her whole credit limit. Hope this helps you understand.
