Unauthorized number cancellation

I have had my Cell C number for approximately 25 years. I recently received an SMS notification stating that my number had been cancelled. After contacting the customer care centre, I was informed that the number was cancelled because it had not been recharged. I did not receive any prior notification warning that the number needed to be recharged or that it would be cancelled if this was not done. Had I received such notice, I would have taken the necessary action immediately. I was also informed by the call centre that it is impossible to reactivate the number. Considering that I have used this number for more than two decades and that it is linked to important services, including my banking application and numerous business contacts, this situation has serious consequences for me. I therefore request that Cell C urgently investigate this matter and reinstate my number as soon as possible. Losing access to this number has disrupted my ability to receive critical communications and authentication messages.In addition, my experience with the call centre was extremely disappointing. After requesting to speak to a manager, I was placed on hold for approximately 15 minutes without assistance and eventually had to end the call. Please treat this matter as urgent and advise on the steps being taken to restore my number.
