Failing to convert prepaid number to contract

I app**** for a contract about 2 weeks ago and an agent by the name of Ashely assisted me. I have indicated in my application that I want to convert my prepaid number to contract but Ashely said he did not see that and the contract is approved with a new number. I refused to have a new number and asked him to redo the application. He redid the application and assured me my number will be converted to contract. I had to wait for 7 days for the new application to be vetted, only to find out that the documents I sent they did not have them... Anyway! I get feedback about the new application and it is approved however with a new number AGAIN! I then request that they cancel the whole deal as I'm no longer interested, to my surprise I received a call today confirming my details for delivery of my phone with a new number. What is so difficult in converting my existing number to a contract. I've been using this number for 10 years and that's the number I want to keep... Why are you not listening to my request as a paying customer and give me what I want????? Or should I port my number to another network which will pay more attention to my needs????
