I have booked an online service from a web site which only asked me for the Debit / Credit Card Info (Visa Electron) to reserve the service (Only save my Card details are saved, no deductions are made until I receive the service).
Unfortunately I decided that I didn't want that service but forgot to cancel it, however, there is not enough money in my debit card on the day I would have received the service. They have not deducted the money, and wouldn't have been able to if they had tried.
If I add money to my debit card account can they deduct any money later? I am scared so am still keeping a very limited amount of money in the account.
