very unprofessional

we agreed to meet in a certain place, we closed the deal and agreed on the amount that i need to add. My unit is smooth and you have no reason to backout since i told him to check the specs carefully before closing the deal so that there will be no hassle when we meet.he agreed and waited for less than an hour for him to arrive. Upon checking the unit madami siya sinasabi na kesyo tampered daw lubog daw ung switch which is a total lie, i even offered him na ipacheck ang unit para makasigurado and in the end lumabas na nga pinapataasan ang add, tsk very inconsistent kausap sayang ang panahon, samantalang siya pa nagsabi na trip ko yung unit nyo

next time ingat na lng kyo upon dealing to this person linawin nyo maigi u might end up wasting your time dealing with this unsprofessional person
