Buyer says item hasn't arrived butno contact from them

[MillyMollyMardy]

I posted a parcel on the 17th April after the buyer paid. They messaged me to say it hadn't arrived at the begining of this week. I asked them to give it a bit longer as Royal Mail don't count it lost until 15 working days.
They said they needed it for a specific thing next weekend. So I said give it until yesterday (Saturday) and let me know if it still hadn't arrived and I would refund them so they had a chance to order a replacement.
They haven't been in touch or left feedback. Do I assume it's arrived?

Yes I would assume it has arrived until you hear otherwise.

Thanks fergoose. I hadn't sold anything on ebay for a while and it's been a real hassle this time. Non paying buyers, a missing item, buyers from abroad. I should have looked at some of the threads here before I listed stuff!

Oh dear - onwards and upwards. Hope your buyer stays quiet.

So do I, bloody Royal Mail and bloody buyers.

The parcel still hasn't arrived. I've refunded and got my Royal Mail claim form waiting. How can they lose a massive great box?
