Bad Customer Service

On Wednesday the 15th December 2021 I emailed Cell C to ask why I cannot get through to any 086 numbers. Today the 21 December 2021 I received a phone call from customer service with regards to this email. They asked for my number and after realising it was a business contract, they transferred me to the business department. This department asked me about 8 security questions and then promptly said they sorry I did not answer all the questions correctly and I must call again!!!! Hello....you guys called me!! The problem is that I have updated my information so many times but apparently they are still incorrect. I have two contracts with Cell C for many years and despite the really bad service I keep getting I have remained loyal. I now am finished!!!
