Kwik COD & Checkout

I've been struggling since day 1, the support is a ghost, which doesn't care even if the customer is willing to pay for the automation services. There is a lot of data discrepancy which these people do not provide any solution, rather give vague replies and most of the times do not even care to reply. I'm trying to find a better alternate and as soon as I get, I'll knock them off my store.
