TROVERR Australia review for PayPal Pay Later Messaging

For the last 6 weeks (admittedly including the break over Xmas/new year), PayPal has been unable to solve a problem of the wrong 4-payment calculations showing on my website when Pay in 4 is activated. I had a call and the problem was clear. Week later another call but the person coming to that call still had no solution. It really shouldn't be this difficult.
