Cell C management do not speak to customers and loss of money

It is fine to not make a comment by cell c when your call ctr. calls in response to the Hellopeter listing. THIS WHEN ONE ASKS FOR THE CEO TO CALL ONE and when the same asked of the call center member who called over a week ago and still no return call from any of the management. Cell C Prepaid if one does not use and one has a large amount of money in the account they stop the number and issue it to another user and you lose your money IS THIS NOT THEFT? BUT FAILURE FOR MANAGEMENT NOT TO SPEAK TO CUSTOMERS IS DESPICABLE.
