Recharge Subscriptions App

We thought based on the reviews that this would be the ticket as we had used another subscription app previously and did not like it. The functionality is good but customers seem to have difficulties logging into their accounts and changing their recurring orders so we end up having to do a ton of CS work on their behalf. Frustrating to only have email as a way to correspond with Recharge CS - would even be willing to pay to talk to someone to get issues resolved rapidly. Instead it usually turns into a dozen emails back and forth trying to explain problems and getting the wrong responses. Am considering a new app again. Frustrating because this one had promise.
