Uter bad service

Never in my life have I experienced such bad service. We visited the Vodacom shop in Brits Mall during June 2020 to upgrade both our phones. A month later my husband received his new phone. Whilst picking up his new phone, he was told that the green one I want is no longer available. So we've selected a white one. Now another month later when I phoned, I was told that the Samsung S10 is discontinued. No message were send to us, no phone call to tell us to pick another phone. Also, for many years, we are on full contract, getting billed at the end of the month for our usage, but suddenly my line is on top up. Today's call was the final nail in the Vodacom coffin for me. When I asked What they require from us to cancel this contract after all these years, she didn't even think twice before giving me the number to phone. Such unprofessionalism I have never experienced in my whole life
