Duplication of Account

In January Cell-C Direct has duplicated one of my Cell phone contracts. Ever since then they have messed-up me banking account never responds back with any feedback. Eventually when they found out that they have made the error I have been struggling to get my own money back. Every time when I phone them they respond to a new ref. number on a ref. number. After numerous struggles and complaints eventually credit was passed by Nonhlanhla on the 5th of June 2015 but they still haven.t transferred the money back into my account and Yesterday again they put a debut order in for over R3000 when my contract per month is R189. just adding more negative reflections on my Backing Account. Their Customer Service is very poor as no-one can tell the truth on whats happening on your account as they give promises of returning your call with answers but never do. I am still waiting on feedback from Brandon Victor who is the billing manager. all I want is my own money back and can't wait for my contracts to come to term as I will not renew them or advise any one to consider opening a contract with them. They owe me almost R3000 Rand.
