We are not in financial trouble but I 'need' to spend a certain amount.on my credit card to gain a loyalty bonus. I could do it in half the time if I pay 3 month mortgage with it. Is this allowed? The Virgin Mortgage website shows an option for debit card payments but no.mention of credit cards. Any advice please? (Obvs the standing.order I normally have with Virgin would go straight to pay off the extra cc bill).
