UNINSTALL THE APP - IT'S THE ONLY WAY!
I've uninstalled the app and I'm ordering direct instead today - the 50p charge (even for cash payment) is ridiculous - apps like this think they can bypass the new law banning fees for using credit cards by charging a "service charge" for all, and the reason that, "all payments involve costs" is a joke... But don't listen to your customers... You go down the drain, and we'll go direct and save money... Ironically for JUST EAT, GREED will be your downfall. £5 they charge the restaurant per order - It's JUST WRONG to be charging the credit card fee by another name!
