Faulty App

Since the App launched its new upgrade I have been locked out of my account. I have contacted customer service and it has been a back an forth between us trying to resolve the issue. The customer services rep is not able to assist. I haven't been able to use my vouchers and I paid for a full year. The customer service rep is ***********. I have been able to use the App in the past no worries but with this upgrade it locked me out. I WANT A REFUND.
