Don't use a Clicks Clinic for medical aid claims

We visited the Clicks clinic for a Vitality Health check and the nurse said we have to pay cash and then use the report from the health check as well as the receipt to claim back from the medical aid. When we tried to claim from the medical aid, the medical aid said that they require an invoice with the ICD10 codes. When we asked Clicks for this, they can now not provide it from the system and we can't claim. I've tried head office and have been struggling with the Branch since the 22nd of May to get an invoice. How pathetic that you can't provide us with an invoice!
