I've sent out over 150 orders in the last month. Three have come back and complained / raised PayPal disputes that they didn't receive it. I've traced that all have been signed for at their property and I've followed up all with numerous emails. Two haven't even replied and one has replied and not answered any of my questions and just repeated that they don't have it.
They are almost certainly trying it on right? I'm doing my best to resolve them and they don't even want to communicate with me
