Oh wow. I didn't even look into their other listing before I purchased. Lesson learnt I guess and I need to be more vigilant. I just don't use eBay all that often and to be honest i am a bit lost as to what to do and who to trust when using it. 

I've sent them an email (replying to the email I got sent) refusing the added cost and asking for a refund. I also messaged them via the contact seller button on the listing requesting the same thing. 

The order is not coming up under purchases (yet?) So what do I do if they refuse to refund me or reply to messages? 

Thank you so much again for taking the time to help me out tonight.
