Cell c for incompetence

Customer service obviously not in there vocabulary. I have been calling for a period of two weeks in connection with my billing and to date it is still under investigation (apparently) how long does it take to sort out a query on an account. First let my account run into a huge amount because of incompetence . Cut my line for two weeks took the money I owed renewed my one contract and not allowing the discount on the new contract . How *********** can a corporate (so called) company be . It's ridiculous
