bad credit recod

My wife decided to do avon about a year ago but being a housewife she didn't have a bank account so we registered her under my name. We were told by the local agent Arina that we need to get orders for more than a thousand rand to activate the account, so my wife went out and excitedly got orders for around R3000 and took the orders to the agent. A couple of days later i was sent a sms telling me i can only order for R1000 because i don't have a credit record with them. So being a little upset with this because now you have to tell your customers they cant get everything they ordered we decided to cancel the whole thing. A while later i get a sms saying i owe avon R858.00 so i contacted them and explained i dident order anything and nor did i receive anything. After a few arguements with the agent and her superior i found out they ordered on my name for this amount and that another lady had received the parcel and signed for it. so they said it was just a misunderstanding and it would be sorted out and that the parcel was sent back. Ok so i stopped getting sms from avon sayin i owed them money. now i find out they black listed me for default on payment???
