LANCET no customer service

Lancet, once again you are useless. I don't think you care at all, as there are more than 260,000 complaints, but you send out a standard message to all with the complaint number changed. I have ONCE AGAIN received a demand for R267 rand, but you REFUSE to send me a statement telling me what this is for. Instead you put the collection agency onto us. What appalling service. I will NEVER go to LANCET again.
