MBD Poor Customer Service

I have an outstanding amount owing to Edgars, which I have made an arrangement with. I was contacted by an Osenotse and we had a conversation around my payments. she explained my situation and informed me what I need to do to stand in good faith. The following day I received a call from Snazo... a very rude person who demanded I make payment and an arrangement. I informed her I have spoken to Osenotse, to which she said there were no notes on the system. I then became my fault that their systems had some issues and she demanded I make an arrangement. I then asked to have yesterday's call sent to me and asked to speak to a manager. she informed me rudely I need to call back to speak to a manager and drop the call. I will gladly make an arrangement to suit all of us, but I shall not tolerate such rude behaviour.
