Rude and unwilling to assist

I spoke to an agent by the name of Zanele in the contract department(staff )she was very impatient and rude and accused me of calling in multiple times where else it was my first time calling in. Is it because am also an agent?. Please treat us the same way as you treat our customers because if i didn't have anything serious to complain about, I wouldn't have called the customer care. Am so angry and dissapointed now i know how a customer feels like when they come through to me complaining about the previous consultant that assisted them.
