Wallpaper smallpaper - me wants!!!!

I've been waiting to pay for all those gorgeous papers I'd taken ages to choose and this morning I received a notice to say the order had been cancelled by the seller because 'I no longer wanted them' which isn't true. I've been writing to the seller over and over to get her to give me an updated invoice with the correct postage. I didn't want to pay £5.88 when it should be £1.50 according to her details. Then this morning I received an updated invoice with postage at £4.50! and that was after the cancellation notice. So what's going on?

I wrote to the seller again requesting the correct postage and explaining that I did want the papers so could she please send me the correct invoice. But... I also explained that I was not going to pay until the outstanding order of 3 papers had been sent. I've been waiting nearly 3 weeks for that. Yet I've already received the first order. I know she's had a bearevement recently and this is probably why things are in a muddle, but she sent that first order during that time. It actually took 6 weeks to arrive! So I thought when she said she was back to work, that it would be all right to put in another order. Now I'm just confused and frustrated.
