Unreliable buyer; made offer and then no response after exchanging mobiles numbers

Made an offer I accepted, countless messages sent regarding pick up, no reply even though the messages had been read. If you didn't want it, a courteous message was all that was needed. Waste of time, rude!

一切顺利！期待下次合作！ 多謝！

時間已經就曬你，先頭話星期六，你話有事要轉星期一，無問題，等等等，等到晚上7點打比你先話唔要，通知一下都唔通知，做人唔係咁樣嗎？
