Called the hotline which was a call centre to enquire about the ART test. Call centre lady was unpleasant, impatient and borderline rude, but gave assurance that I would be able to take the test upon walk in. Requested for the number of the medical centre but was flatly denied. Upon arrival at the medical centre, turns out they had a system error and is unable to conduct the test, referred me to their other branches. Extremely disappointing service at the call centre, further disappointed at the medical centre for the lack of solutions even after explaining my circumstances and sharing possible solutions. Dismal waste of time, not recommended at all.
