Utter incompetence

Complete and utter incompetence!!! Can't even allocate a payment against an account so instead they continuously send threatening messages saying that I will be handed over if I don't pay. Proof of payments sent as required and they still can't get it right! If this is just one account they can't get right, how many other's are fighting the same battle? If you can't add, then you should not be in this position!
