CELL C SERVICE IS A DISGRACE

Can someone please give me the CEO or MD email address for Cell C. The service i have been receiving from them since the inception of both my contracts has been appalling. This CANNOT be the standard of service we PAY for. I had processed an upgrade in March 2022, the device delivered to me in April. I did not want the device and returned it. Now today i receive a SMS saying my upgrade has been processed and i need to approve the debit order on my banking app. When i call into Cell C, person after person department to department they passing the buck but no one has assisted. I am sitting with a bill possibly at the end of June 2022 and no device. The agents are expecting me to call the deliveries team, then customer care, then accounts and upgrade to resolve. This is PATHETIC. I need to cancel both contracts and NEVER do business with Cell C again.
