avon account

I haven been trying to get hold of Avon however i am not able to since i do not get response via email, and i cannot be assisted on calls since they require a pin of which i am not sure which one is that, i needed to find out if i can re use my account after having to pay the outstanding balance, i have been on your whatsaap site still there is not response and the agents on call also does not know how to assist me.
