Upgrade that was not done...U lie to customers for sales

Im complaining about a Simphiwe Ndidi who called me on the 28 july 2025......who **** to me and told me that they are upgrading my contract and instead he did not do that, as he just added another line. That means he **** and misleaded me. when i call they tell me that they must investigate, which is totally unacceptable that your agents dont do their jobs properly. If i did not call and enquire it means i was going to be billed for 2 contracts instead of one contract, so basically that means u lie to customers inorder to make sales. i spoke to the below Heidi Thomas senoir agent, stand in...who reports to Poovarsha Moodley.....and the said they will give feedback on the 13th August from Robin Abdie reference RCO681915. I want this issue sorted out urgently or else come and take back ur device. Totally bad service. Im extremely upset.
