I made an offer on an item of £7.99 and it came with £2.30 postage ..I won but it now says postage is £20 and it says I have paid £27.99 I tried to pay through the invoice i received which was for the correct amount of £10.29 but when I clicked on it to pay it showed on Ebay as £27.99 again... I have contacted seller but no reply as yet and I cant get a phone number to speak to ebay agent
