Pathetic Excuse, I want my number bac****!

I defaulted on my vodacom contract. I had been retrenched and was not able to to pay for a few months. My contract was then canceled by Vodacom and my number has been deleted forever as I have been told and been handed over to collectors. Now that i am on my feet again I can pay the amount outstanding which is 30k. I am willing to pay this in full if Vodacom gives me back my number which I have had for 16 years. All i want is my number back and i will pay in full but i keep getting told they cant, if they cant i will pay R100 per month until the outstanding balance is finished. Vodacom, you cannot tell me you cannot give my number back in this day of age and technology
