No refund from Lancet for analysis not timeously

Lab ref no. Y*** dated 5 or 6 June 2014. Specimen for analysis given by the Specialist to the lab at St Augustines hospital in Durban. To determine the type of infection for the correct treatment. A EFT payment was done into the labs bank account and confirmed to them, yet a week later the analysis was not done. The Specialist rooms then called the Lab that the analysis is now longer required as a week has passed. I also called at the said Lab and advised them of the same and requested a full refund. No one at the Lab seem to interested to assist or accept responsibility for the bad service. Not even an apology or excuse given. Many promises telephonically to me and my wife for sometime thereafter that they would investigate and come back to us. No one ever comes bank. A company and staff of no integrity and that in a Medical field ! The amount concerned is R887.00 Really shocking and disgraceful to demand payment upfront and then after all not do the analysis, which by the way was required for infection after skin graft for cancer removed!
