WHO IS VODACOM TO DECIDE ON MY CELL PHONE NEEDS AND DUAL SIM CAPABILITIES ?!

so I upgraded my contract and decided to switch to Vodacom. probably the biggest mistake of my life so far... I ask for a cell phone with dual sim as Im starting a small business and I prefer to have 2 sim cards when it hits off. well its hit off and now I discover and have been told by Vodacom that my phone (Huawei p20 lite) does have dual sim function but its been deactivated by Vodacom. when I asked for reasons, what the agent regurgitated made no sense to me at all. my contract is a mere 3 or 4 months old and im on the verge of switching to Cell C as they offer more affordable prices to data for my small business needs. besides the false advertising and the blatant ******* in terms of data costs compared with Cell C, I am livid! Vodacom I challenge you to explain the reason for this dual sim deactivation to me and also hopefully save yourself a client/contract here. I see all over HP that I am not the first and only customer that has this same issue!
