Billed monthly with no account!

I ordered a iPhone 6 plus from TELKOM last year. The phone was out of stock and I received nothing for over a month. I contacted telkom to let them know I didn't want it as I renewed a contract with MTN (a far more superior network). Two weeks later a handset was delivered to my office. (CONNEXIONS CHURCH - Ordered by Connexions Church) I contacted Telkom and instructed them to collect the handset as I was no longer interested. It took them 4 days to send a courier to collect the handset. The Courier arrived and instead of collecting the handset from me had wanted to deliver a second handset. A service center agent requested that I five the handset to the Courier and that both handsets would be returned to Telkom and the account would be closed. This was October. I am receiving monthly accounts for R499. I contacted Telkom which informed me that the account was cancelled. I received another account this month. I went into a Telkom Store and the query was forwarded to head office. I have heard nothing since then. Telkom, once again you are involved in bad business practice. Please sorry this out immediately. I will never do business with you ever again! Pathetic service.
