Dishonest Telkom Consultant Causing Me A Lot Of Trouble

About 2 months ago I went to the telkom store in the Kollonade shopping center to take out a contract on a Samsung phone. When I entered the store the consultant at no: 2 told me that they had absolutely no stock of any Samsung phone whatsoever. I decided to take Huawei P40 Pro, because I was in urgent need of a phone. Before finalizing the contract I asked the consultant from telkom as well as the consultant from Huawei if I would be able to load any android app on the phone and they assured me that I would be able to do so. When I got home I tried to install the invoicing app that I've been using for a couple of years, called tropic invoice, but I was only able to install the free version. The Microsoft authenticator app that I use to login to all my client's website was also not working correctly so I returned the phone a day an a half later. In the store both consultants tried to get those 2 apps to work correctly without any success. The consultant from telkom then canceled my contract and asked me to wait 2-3 weeks before applying again. After 2 weeks I returned to the store only to find out that they had Samsung phones in stock all along. I then took out a contract on the Samsung Note 20. After the first month my bill was correct but then on my second bill they started charging me for the first contract that was canceled as well. After sending multiple emails and visiting the store twice my account is still not corrected. I need someone from telkom to contact me asap and have my account corrected so I can pay my bill. I also need telkom to stop trying to take this incorrect amount from my account. I will not pay a cent towards my bill before it's corrected. I am not willing to pay a cent on the previous contract or Sim, because your consultant and the consultant from Huawei **** to me about your stock situation to promote Huawei sales and also about the software ability of their phones. This will be my last attempt trying to get my bill paid. If you are not willing to contact me and correct your mistake then go ahead and put me on ITC.
