Bad customer service

My wife has a few contracts with Cell C, she is busy with chemo therapy and is not very well. She called Cell C and cancelled a contract in 2025-01-01 also emailed them. This was an old contract and was on a month-to-month contact. Now she found that there are still charges on the account, she phoned them today and she was transferred from pillar to post, indicating to me a total lack of customer service and incompetence. She was told there is still usage on the phone referring to data and itemised billing. How do Cell C then still charge her after notification was email and she phoned them to cancel the contract. This phone contract was used as a site phone for one of my employees. The site cancelled and we will not need this contract any more. The employee is also no longer working for us as his employment was terminated when the site contract expired. She phoned Cell C again and said they need to stop the card or block it. One way is to report it as ****** as the x employee is using data that he loaded and self-paid for. My wife had to answer some security questions as normal, but one question was, with how much was the data loaded. She will not know as she did not load it or can see on the app. She failed the security questions and was told now they can’t help her. She was on the phone from 8 o clock this morning and now gave up as no one can help her, the time now is 12 o clock. It seems the Cell C staff is deliberately playing games with their customers while they do not care if she is sick or not. Is this really the customer service we as the public must be happy with. I want to warm the public to think very carefully if you take out a contact from Cell C, as when you take it out, they all helpful and smiles and it is just wonderful. Try to cancel the contract, then you see the real customer service, totally degusted and I will never take out a contact with Cell C. In the meantime, the account is still running and Cell C is making money from this, I see it as ******ion. If Cell C have any customer skills, and hopefully value their business as a service provided in SA, they will now phone my wife and rectify this matter. Let’s see what happens. Account Number: ***2
