Ever hopeful of resolution

I suffered a heart attack and while in hospital had extensive blood tests conducted. One account alone was for R17,500. My medical aid deducted an amount of R346 as the tariff charged was for an incorrect amount and they advised Lancet of this. I also sent 5 different emails to Lancet explaining why I would not pay this amount but haven't even had the courtesy of receiving a response. What I do get on a weekly basis are threats from different collection agencies that so distress me that I fear I may suffer another heart attack! If anybody reads this at Lancet please have some compassion and credit my account.
