Complaint - Contract terminated with no notification 2nd Complaint

I am extremely disappointed with the service from Cell C today, I had logged a hellopeter on the 24th December 2020 and my query was resolved The agents were excellent with resolving my query, having my number reinstated immediately and a payment arrangement in place. I am now faced with the same situation. In 2020 a payment arrangement was in place and Priscilla from Collections handled my query ever since with no issues or concerns the best service ,considering my situation with having to close our business due to the pandemic . This morning I receive an sms that my contract has been terminated with no indication why, no one had bothered to contact me prior or inform me on the reason.The payment arrangement has been done as per the arrangement. I have not access to make or receive calls. I visited the Cellc branch in my area and was assisted by a friendly agent who contacted the call centre on my behalf and we were advised by the agent that due to me paying 5 days after my debit order date my contract has been cancelled. This is ridiculous, how can this be the case when I had already have a plan in place and no one has mentioned to me that this is a concern, I am unable to have my number reconnected although I have a plan in place or changed to a prepaid with my current number, I am utterly distraught as I have this number for the past 15 years+ and my number is the only contact with my livelihood. I would like for my number to be reinstated immediately alternatively provided with an option to keep my number on prepaid. I have little children and rely on my phone for day to day and emergencies. Please can my query be reviewed urgently.
