Very Bad Service

I called in the Vodacom Center to do a cancellation and I was assisted by a lady called Nokubonga Prudence Cele. I asked her to give me her surname and she started getting sarcastic and she responded by saying her surname is the same as my surname. Secondly I asked her to assist me with a cancellation she she advised I can only cancel my contract around November, I started fuming and she did not take me serious at all and ended up hanging up the call since she was useless to assist. I called in again and I was assisted by Samkelisiwe Cele whom immediately said she will assist in my cancellation and without any hassles she did the cancellation and also spoke to her Supervisor whom gave me name of the Agent that I spoke to who is the so called "Nokubonga" she's got the worst pathetic service I have ever came across and am worried with Vodacom if they keep such rotten potatoes, it will affect the others who know on how to treat a client.
