I've ordered successfully from you before (and I'm waiting on some Lemon Haze now!), and your feedback rep is stellar, so I'm going to assume that you've truthfully sent out both orders as you say.If you're client is realistic, they'll also come to the same conclusion.I think you have to give it 10 more days before you make any decision. Yeah, that sucks for your client who's waiting, but you don't control the worlds postal systems.I've never lost a UK package, and currently have one to the US that's in limbo, and was even sent Airsure with Track and Trace, so I have great hope that it will show up. But I did have a UK mailing that both I and the client thought was lost. Instead of 2 days, normal, it was getting over 2 weeks, and I was waffling between thinking the Post Office were idiots, and maybe - just maybe - the client was trying to have one over on me.Then I get a PM - the fucking thing had arrived! Apparently the sorting office on his end weighed it - whether on a scale or by eye - an decided it was too heavy for first class, and re-marked it as 4th class mail. (I'd add this really pissed me off, because when you mail First Class in the UK, if you go to the counter they can - and you have to be firm on this - give you a Certificate of Posting - which is not the same as a receipt, because it's got the weight of the item, and they also punch in the house number and post code.) It was 1 gram under the weight for the next upcharge for postage, so I did in fact have the correct postage on it. That didn't change the fact that it was treated like 4th class mail just for being 'close' to being over weight for the charge.So, when you figure it may have got bumped down in priority like mine was, or Bob took a couple days off in the sorting office for that area and they're behind, coupled with the standard Christmas mail rush, both packages still stand a great likelihood of still being delivered.At the very least ONE of them is going to make it there.Now, you've dealt with this customer a few times, so you have to consider that too. If I was you, I'd whip up a care package - maybe 1/2 what one order has in it (assuming it's not for a qp) and offer my client this: I'll send out the care package, worth X, Special Delivery, tomorrow, so they'll get it the next day. If their other packages arrive, they pay for the care package and release escrow on the 2 orders. If it doesn't arrive, no charge for the care package, but no further refund either. Have it agreed in PM so if it goes to resolution you're covered.And hey - where the fuck is my Lemon Haze?
