Vodacom Agent Rude and unprofessional

A consultant from Vodacom contacted me with regards to a contract. I have a contract with Vodacom which is currently active, however this contract contradicts in terms of dates. I then requested the agent to check for me the date which for the existing contract he said I took it in February 2019 which is not true, the contract I have I've been paying since early 2018. I then ask if he can refer me to the right person or number where it can be checked for me.

The Agent was rude from the beginning when he realized I have an existing contract with Vodacom, I tried to calm him down which he then dropped the phone without assisting me from what I was asking. If this is how the Agents behave, I would advise everyone to stay away from this network. I am taking my business away from this nonsense. After a long time I've been with Vodacom I don't see myself continuing with them. My family is using Vodacom but from today good bye. Here is the number of the person contacted me ********** 540
