Disconnected Without Notice. Nightmare to Resolve Account Issues

I have been struggling with my account for the past month and a half where they simply disconnect a number without notice.

I have more than 1 cellphone number that uses the same account number (as per statements) as a payment reference then when I ask them how they allocate these payments they cannot give me a direct answer and my daughter's phone has been disconnected for a month now where I paid each month.

It is a nightmare to try and resolve account issues with Cell C. When you have more than 1 phone number that uses the same payment reference then surely you can tell me how it gets allocated? The amounts I sent the proof of payments for also didn't reflect the same on Cell C's system when I spoke with an assistant.
