Woolworths unacceptable credit provider actions

Recently I was contacted via SMS by Woolworths stating that they will be reporting me to the credit companies for non-payments. I phoned them to inform them that I have made payment and they informed me that due to their systems that takes 2 to 3 days for processing the payments - this actions was now taken. When I asked when they phoned me as per requirement, they said the call was dropped and this was regarded as contact with me. They cannot provide me with the call or proof of the call. My payment was made as required and Woolworths did not comply to the required actions from a authorised credit provider. My legal actions are in progress to expose this unacceptable actions from this credit provider.
