I used the service for a number of years as an expat in the US. I was part of the group that was charged $699 earlier in the year instead of $6.99 monthly. I had to cancel my credit card as a result and to be fair, BB did provide 3 months of service free of charge by way of apology. However, when I went to enter details of the new card they were not accepted for some strange reason. My new card works in all of my other accounts but after 5x repeat emails back and forth with their 'customer service' there is no apparent remedy other than suggesting I please 'check all my details' again. Obviously something central to their system is the pivotal tie-in to the original credit card when an account is formed [mentioned by others on this site] but updating a card should be straightforward and not a customer problem in this case [insult to injury is that the new card was necessitated by their monumentally bad billing error]. I am sorry they have trusted web security to an untrustworthy and inept supplier, but I am now a relieved ex customer.
