Hotel took 2 payments - different card

Humbug1929

Hi, I'm hoping someone can help if possible.
We stayed in a hotel in London - payment on arrival. Paid with one debit card Lloyds - the machine froze giving no receipt and nothing showing on the screen, the lady who was the manager said the payment didn't go through. They rebooted the machine and we paid on another debit card Monzo, this payment said on the screen it had gone through.
Payment from first card said pending on online banking - hotel said this can happen and it will just disappear as it didn't go through on their end due to the frozen machine. (I have had it before where a pending payment didn't go through when there was a problem/cancelled payment so I didn't worry too much - obviously learned my lesson now!)
A few days later we rang the hotel, they said it can take 5 days for the cancellation to show on the bank.
Fast forward after that time, we spoke to the manager as the payment had been taken out of the Lloyds account. Manager refused to co-operate said they only have one payment on the system for our stay and said when we sent screenshots of Lloyds and Monzo that it looks like it's from the same account (very obvious this is not true). She was very rude, kept interrupting and would not let us speak to the accounts department. I said on their accounts they would have 2 payments under the same name within the same time frame etc. She refused to acknowledge anything we said. 
Spoke to Lloyds - explained and sent screen shots. They refunded the money and said they would take it up with the hotel. If we didn't hear anything back in 10 days then it was sorted and money was completely refunded.
A month later and the money has been taken out of the account again, after speaking to Lloyds again there was a standard "it may take 45 days to resolve your query"
Can anyone offer any advice please?

Frozen machine does not stop a payment going through. Typical staff that have no idea on how the systems work.

If you have been redebited then hotel must have contested the chargeback. You could get lloyds to go back on pre arb on the basis of proof of payment via Monzo & Visa/Mastercard will make a decision.
If that fails then.
Start same process with Monzo.
If they contest that payment. Go back to Monzo for pre arb, on the basis that they have already taken the payment via lloyds
