Pret A Manger has refunded subscribers who have been unable to use its app since it introduced a crackdown on subscription sharing.

The Telegraph reported this week that some subscribers to “Club Pret”, which allows a customer to order up to five barista-made drinks a day for a monthly fee of £30, were experiencing technical issues with the app and were unable to claim their free drinks.

Subscribers must now use the Pret app in order to claim the free drinks rather than accessing their QR code in their Apple Wallet or on a smart watch, under new rules that came into force on March 18 to stop people sharing their subscriptions.

Pret has now told The Telegraph it has given refunds to some customers who have struggled to log in since the changes came into effect.

A spokesman for the company said: “Since we made this change in March, our team have either given refunds or applied the Club Pret discount as normal to any customers who have genuinely struggled to log in.”

Since the crackdown on subscription sharing came into effect last month, some subscribers have complained about being unable to log in to their Pret app to access their QR code as their password was not recognised, while others claim they were told the SIM card in their phone did not match the phone number linked to their account.
