How long?

[badguider]

I bought something in auction ending 1st Sep. paid by PayPal same day.
Item said est del by 4th.

I haven't heard anything at all and it's not marked as despatched.
I messaged today.

How long do I have to wait for a response and what do I do next?

Thanks.

wait 24 hours then open not received case I reckon.

Ok. Thanks.
I've been lucky so far and have never not received before :(
