I sold and posted the item yesterday but when trying to enter the tracking number onto the sale it says the number tracking has already been used before. I am guessing another seller has made an error &nbsp;but how can I enter my tracking number if somebody else has wrongly entered it before ?</P> Sun, 05 Mar 2017 11:42:29 GMT mywonderstuff 2017-03-05T11:42:29Z https://community.ebay.co.uk/t5/Member-To-Member-Support-DO-NOT/tracking-already-used/qaq-p/5261773 <P>I am trying to enter my tracking number from the Royal Mail .
