Rude service agent, when Vodacom is the one that messed up my contract and gave someone cellphones under my name

I found out that vodacom issued someone with 2 iPhones without my knowledge, there could be more I don’t know as I cancelled a 3rd one which was a Huawei P50. Even went as far as doing a sim swap and changing my email address. Now that I have opened a ***** case with Vodacom, following up in a nightmare. The lady who is meant to answer *** probably has not been trained on customer service. She didnt give her name, told me she’s tired of people calling to check up on their cases, rudely tells me it’s too early to check up. When I asked her, “why are you being so rude though?”. She actually hung-up and when you call back, there is no answer. Mind you I’m the one who’s a victim due to Vodacom not protecting my contract, yet have to deal with a rude Vodacom service agent. I called at 09h52. Pity I cannot give a negative
