No communication for 3 months

I serviced my car at a Bosch service center and as part of discovery insure we receive a discount based on our vitality drive status (which I take seriously). The system was down/ off line whatever the story was, so they contacted discovery who said just forward the payment to discovery afterwards and we will refund the discount to the member. This was done November 2, we are coming up on 3 months ago, and 3 emails by myself to follow up on this. Can I have any kind of feedback here? I get the automated response, but are the relevant people still on holiday, what is happening here?
