I too have had problems with donations. I didn't find the response exactly helpful.
Caffe Nero used to donate 5% of
what you spend if you registered a credit/debit card. with E/F and used it to pay. At this time drinking their coffee
2 or 3 times a week as a group. I usually paid on the reg card and was reimbursed. Noticed a few donations were missing
the reply was Caffe Nero withdraw from the scheme in March.
A pity not really E/F fault but a loss of a nice little 'earner'
Keep spending every one and always use E/F if possible
Bear thanks you on behalf of all the dogs
