Disgusting contact center service

Just called into your call center, the lady i spoke to did not understand what the word credit meant, I then took the liberty to spell the word for her and then she just dropped the call in my face. What kind of service is Makro providing to clients? All i needed to know was do i need my original ID with me when purchasing on credit or can I provide a copy as I do not want to make a trip to your store just to be told i cannot purchase without an original ID.

Please look into your contact centre staff as this is unacceptable service being rendered which will drive loyal client's away. really disgusted by this woman employed by Makro
