Travel Company Online Payments System Took Too Much Money From My Account

[Corrie_fan]

I recently tried to pay some money towards a holiday using the travel company's website. The transaction failed, so I tried again. It failed again, so I rang. They couldn't see the transactions so assured me there was a problem with their online system and instead took the payment over the phone. A couple of days later, the two "failed" transactions came back to life and worked, leaving me over £900 down. The travel company has issued a refund to my debit card but the bank informs me this can take between 1 and 7 days to process. In the meantime I have £26 to my name.

The bank have suggested I extend my overdraft which I have done, but I don't like using an overdraft and don't see why I should have to when I've done nothing wrong. I know this will all be history within the week, and I'll have my money back in full, but I've spent all morning on the phone when I should be working, I've been worried and I feel I should be recompensed by the travel company who took the money erroneously. Surely they should exercise due care in their computer systems to ensure this can't happen?

Is it worth pursuing some sort of compensation for inconvenience? They have been negligent and I think there should be some sort of consequence.
