Just to clarify,
Are Marriott recalling
ALL MR points transfered to Tesco Clubcard Points, even if this was done before March 8th, with seemingly no credit card or system problems?
Or does this 'recall' only affect people whose MR account went into negative balance for one reason or another?
In other words will I finally become a BA miles millionaire, or am I still likely to be scrimping and scraping miles come the May Tesco statement?

I think that Tesco points have only been pulled back from those who spent their "bonus points", i.e. the MR points which mysteriously appeared in their accounts in error.
