I normally send my sales via click and send, but in this case, the item, although less than 500gm, was too big for the bag, so I could have sent it in a 3kg bag, but felt that this would be quite expensive, as I normally charge $13.  Also the click and send bags may not have offered as much protection as the box I did send it in.  I charged $10 for postage and the parcel actually cost $6.95 to post.  The buyer has now lodged a complaint through Paypal saying that she received an item that was significantly not as described and is claiming $3.05 to be refunded to her (the difference between the cost of postage and what she was charged).  Because of this claim, my Paypal account was blocked, which after 3 phone calls to them, I've now had unblocked. With click and send, everything is done online and my post box is half a block up the road.  In this case, I had to find a suitable box, seal it all up, get to the post office by car, wait in the queue etc.  On top of this the buyer didn't pay straight away and after my second email to her she responded saying she was having trouble with Paypal.  I offered to wait until she'd sorted out her Paypal issues, so long as she kept me up to date.  Long story, I know, but I feel the buyer is being unreasonable and I was hoping someone might have some advice as to how I can deal with this.
