Horrible, ***********, screaming agent

I bought a contract at vodacom on 01-04-2017 for two cellphones and a laptop. One of the sim cards they gave me have never received any data that im paying for it to date. I have been sent on a goose chase since April and finally got kicked out of the store. The agent didn't even check the information from their system, she told me what "she think could have happened" and then when I asked why is she not checking on the system, she started screaming at me telling me that I don't have a *****ing* clue how they work and I should stop acting stupid and listen to her... When I responded and told her to give me a verifiable constructive feedback from a system as to what is happening to the data that I was suppose to receive since April. She called security to come and escort me out and she **** to him saying I'm not a customer and I'm harassing het. This happened at shop no 31 CNR van der walt and church str in Pretoria on the 28-10-2017. Even today I'm paying for service I'm not using
