Lancet Laboratories Morningside-Sandton. *********** service

Very *********** service at lancet laboratories in morningside. Mixed up my data with another patient and refused to take my calls, making false excuses that am rude. Hung up my phone calls and refuses to give their name when i called, leaving me with no way to record my complain. Referred me to the national call centre instead of hearing my concern with the mixing of my data with another patient. Very unprofessional service
