Woolworths vindictive practice

I app**** for and was granted a credit card by Woolworths Financial Services in 2012.I subsequently had a financial difficult period when i couldn't pay my full monthly instalment and app**** for debt review. Woolworths initially accepted the agreed upon amount but continued charging interest, the amount rose from R21000 which was my limit to R39000.I had endless call from the company though they still received their monthly payments and in protest to their ever increasing interest charged on the amount owed I stopped the payments until it came to a point that i was handed over to their lawyers, Luyt and Brooks. I made an arrangement to pay R600 per month outside the debt counsellors arrangement which I subsequently cancelled. I have been paying through their lawyers ever since and have never missed any payment. However my credit profile reflects an amount of R24430.00 as both my instalment, overdue amount and my current balance. According to the enquiry i made in April from their lawyers the balance was R18000 and a few hundreds. I contacted the lawyers to correct this and show that I am paying this monthly R600.00 towards reducing my debt but thst hasn't happened and they told me that will only happen after the account has been settled. My concern is, is it legally acceptable for Woolworths lawyers or Woolworths to send the incorrect information to credit bureau simply because they can do so? When I asked the name and contact details of the credit bureau they use in order to rectify this anomaly myself, I was flatly denied.Why such vindictiveness? I don't know as it is how much is my balance despite requesting it.Can Woolworths confirm to me if this is how they treat their indebted customers or if they accept the way their lawyers deal with them(customers). I demand that my monthly instalments be reflected on my profile and the balance be correctly indicated, like all other creditors. I also expect quarterly emailed statements as agreed. PR Hlayise.
