I had a terrible experience with Vodacom

I had a terrible experience with Vodacom. My phone was ****** with my pre-paid sim card, which I use for my in-contact banking, I sent my cv out using that same number. I've used this sim-card for years. I've lost many opportunities because of not being able to do a sim-swap. I've called-in. Contact them on their social platforms. Unfortunately, they are refusing me a simswap. How am I supposed to know how many phone calls, Airtime was used when my phone was ******. How am suppose to know what the ******* were doing on my simcard!!! I told them the last details I remembered when I used my sim. Even my in-contact banking is there. I'm so disappointed and I've used this sim-card for years!!
