Frustratiing Customer Care while abroad.

I have been overcharged on my monthly contribution because the debit order has never been adjusted. After various emails to request adjustments, it was confirmed that it was indeed done and yet they still deduct the incorrect contribution. The calculation I did and forwarded to them amounts to more than R14 000 they need to refund me and asked for confirmation on this, and yet no refund nor confirmation. Sizwe Hosmed Medical Scheme's administration is absolutely in shambles and has at this point no intention, ability, or skills to resolve this frustrating experience.
