Backout buyer. Made an offer 30.08.17, notified me that she didn't want the item anymore on 11.09.17. Thanks.
UPDATE: To be factual, bank account details were provided on 02.09.17 and buyer had informed me that she will make the transfer 2 days later. However, buyer informed that she didn't want the item on 11.9.17. Look who was unethical. Facts are as per above. If no one is home to collect the parcel, you can always communicate and explain that there is a delay. However, no explanation given
