A year ago, I purchased an 0845 number for £9.99 from a company called UK2Numbers, which is a subsidiary of IM-Software. They advertised the service as being a one-off fee, so I decided to purchase the number, but in the end never used it. Last week, they debited £35.76 from my debit card - they obviously held on to my debit card details and left their telephone number as a payment reference.
Now it transpires, they expect me to pay an annual subscription fee for the number, which I would not have opted to do if they had contact me to ask in the first place.
Are they allowed to do this? Charge my card a year later, when I was told there was a one-off fee for the 0845 number?
Does anyone have any advice in this regard?
