Terrible Vodacom Telesales calls

I received a call from one of Vodacoms sales agents this morning. Explaining to me the new packages on offer and he can save me money, which does not make sense, because i need to pay R160 more per month. He argued with me after telling him i do not want to change anything. After telling me its not an upgrade or selling me anything! Then when i told hom thank you but really i am not interested he die not even say goodbye, he dropped the call like an immature kid that did not get his way! I was a call centre agent for Outsurance and never in my life on the job did i treat any customer this way. Even if I did Outsurance would most certainly have called me in for disciplinary action. Wheny contract term is over i will most definately cancel with Vodacom and move over to MTN. This was not the first time Vodacom has treated me badly and i am tired of it. If one of your agents call me again it would just be F... off!!!
