I received the email saying that I could sign up for an account. The app was loaded on to my iphone and I entered the details for the £100 topup.
The app then said that my card was declined but I should try a different card. However when I check my account there is a £100 difference between the available and actual balance so it appears it has been processed.
How do I get the £100 refunded as I cannot go any further with the mondo app and I am not going to have another go at loading another £100 on the account.
