I have sold an item, buyer is a newbie(0) feedback. Her postcode and the city don't match.  Seems she has put a city in, NO suburb.

I have messaged her to correct it in Paypal and eBay before I can send the item. However, in the past I have come across many who put the suburb and also the city in, and labels won't print as they have put the city in the suburb line. I had one customer I told about it, and even though she corrected it, it did not correct on the address I was seeing, so I supect it would only be correct for future sales. So this is my dilemna...even if she does correct it, I cannot send the parcel to an incorrect address if I do not see the new address, so do I need to cancel the sale and tell her to rebuy when she corrects her address, so that the correct information comes through to me? If I need to cancel the sale, and I select "something wrong with the buyer's address" does she have to agree? I wouldn't think so. However, way back I had a buyer from Spain buy from me even though I am only selling in Australia, I cancelled the sale and marked it "buyer is in a location I don't send to" and he still had to agree to the cancellation. Also, would I get a defect for cancelling? Your advice is very much appreciated.
