Paying for a contract which I am unable to use

I app**** for a new contact with Cell C. They had to port my number from Vodacom to Cell C but to date, that still hasn't happened. It has already been 2 months since I had app****. They have debited my account once, for pro-rata and twice for the actual payment of the contract. How is it fair to pay for a contract if I am unable to use the benefits (data, airtime and minutes). I have contacted the call center once, and they said that it will be done within 48 hours. To date, NOTHING has happened.
