Barclaycard Cashback Card

I used to have a Morgan Stanley credit card - it gave a pretty fair
cashback, and as I paid off the balance every month the interest rate was
great!
However, Morgan Stanley in their infinite wisdom have transfered all their
credit card customers over to Barclaycard - with a new cashback card. This
card has a number of advantages over the old Morgan Stanly card - the
cashback is put onto (credited) to your account each month rather than
accruing and having to be reclaimed, and it has the new contactless
payment system built in - even though this is only available in London at
the moment.
But - yes there's a bloomin great BUT. I tried to set up the account on
line so I could set up a Direct Debit (now there's another subject!) to
pay the balance every month but Barclaycards servers are having none of
this - after multiple calls to their Indian call centre (on an 0844 number
-heaven alone knows what that's cost me) they finally told me that the
servers cannot register the migrated Morgan Stanley cards.
So with trepidation I will change my PIN and make a couple of test
purchases, and we'll see what happens when the bill comes (or if I'm in
luck no bill will come, ever!)
