Bought subscription but app suddenly giving unexpected errors

Bought subscription but app suddenly giving unexpected errors when trying to order online or pay with app. This means that if they create the system error they can literally **** you out of the deal they advertise which is 15 smoothies for 15 days. Please don't buy their subscriptions because I believe the system error is artificially created to inconvenience the customer because lets be honest not everyone signing up will be able to come again on the same day. Very disappointed to have been ****med like this. I will continue to try and order online and see when the redeem system is working again but this is not branch related because it gives the error on both online order and pay with app. I did buy a subscription, I visited the branch with my phone and adequate data and my app is updated so I did everything on my side to honor the subscription contract and it's paid upfront. Now it's your responsibility to deliver. This should be reported ASASA.
