eBay

I have commited to buy $178.95 worth of jewellery,I also bought a EMS postal service for $25.00 from the seller,the seller wants me to pay a additional $29.00 in postage I emailed the seller telling them i dont think thats fair as i am already paying...

The package number given for my order doesnt exist in the postal system it supposedly has been sent by.I have emailed the seller twice requesting a explanation but have recieved no reply.
