This is quite worrying!
A lot of people have been charged twice in the supermarket.
This affected the Co-op on 7th July 2015 only.
Customers who made a purchase from The Co-op stores or petrol stations on this date and paid using their credit or debit cards, have been charged twice.
This has left some people in financial difficulty and some have even gone over drawn.
On Sky news, a spokesperson for The Co-operative Food said: “Due to a processing error customers who shopped with us or used a petrol filling station on 7 July using a credit or debit card were charged twice.
“We would like to apologise to all those affected, and reassure customers that refunds will be made directly in to their accounts within 24 hours.
“We will also reimburse any customers who have incurred bank charges as a result of this error. These customers should contact our customer careline.”
