Very frustrated

An agent placed an order for me, as I was still learning the ropes, being a new representative. When received my order, in the box was a batch of catalogues and flyers. I immediately contacted Head Office via email, informing that I did not want the catalogues, (as they are only valid for a month) I got an automated reply. I then received a phone call from the accounts department saying my account was in arrears. I paid for the products I had ordered but did not pay for the other items, which I did not order. The gentleman I spoke to said he would look into the matter. The next communication I received was to tell me that they were adding a further R50 to my account as it was still outstanding. I called Head Office again and was told that they would pass a credit for the catalogues, but couldn't pass a credit for the additional charge as well as the membership fee. I told them I did not want to be a member and I was not paying the additional R50. I have made numerous calls and sent a few emails and nothing has been done about this. In fact, they are still chasing me for the money. I will not do business with a company who refuses to address my problem from the first time I complained. This has been a very disappointing experience. Communication sadly lacking
