Can't get cell phone contract

I app**** for a cell phone contract with Telkom on 21/11/2015 (ref nr A***). The lady (Gloria, who was very helpful) told me there was an outstanding account that needed to be resolved first. She looked into it, and found that Telkom owed me just over R1100!! I went into the store again on 24/11/2015, only to find out from the gentleman who helped me that nothing has been done, because my account hasn't been settled yet! I could sent in an email to ask for follow-up, but couldn't call because there phone lines didn't work?????? I therefor cannot get a Telkom cell phone contract! Congratulations Telkom! Besides the three contracts that I was about to switch to Telkom, I will now also NOT apply for the re-installation off an ADSL line. I don't have ANY debt, yet Telkom refuses me a contract of R350/mnth. I'm sure another service provider will help me without any issues. The only question now is how do I get my money that Telkom owes me back? And how do I cancel my application?
