Disrespectful call center staff

Good day

i'm sadden by the poor experience received by your sales consultant Steven, I contacted by Steven to sell a data bundle package, in which i requested details of him as i wanted to compare between what I currently have and what he was trying to sell me, to make a clearly and concise decision, in which i declined the offer as it does give me something new or match what i would like. Steven then continued to shout and tell me that i shouldn't have wasted his time and dropped the call after tell me off.

This happened yesterday at 10:50 am from a ********** number.

My request to vodacom is to please take me off any marketing leads or new products they want to sell to me. I was disgusted by the uncalled outburst from Steven.

Thanks Glen
