Confusion re balance and payments

Good day I would like someone to please contact me regarding an account. I have had interactions with five people who has given me different information on different occasions. I have been paying the account monthly, received a statement but when the agency called me they had an amount that was double.I was then contacted again by Blake and told that I owe R500. I email Blake and they then apologise and say that the information is incorrect. Blake then calls me again with conflicting information.In the meantime I receive a call from someone else saying there was a mistake and that the balance is less and that I must email payments.She has never rep**** to me again.Vanished..in the meantime Blake is calling with a new balance each time they call. I am totally and completely confused and it seems everyone else is as well. Can I please liaise with ONE person that can actually give me accurate information.
